The Technology Behind Them

Albert Einstein, a famous scientist, developed the notion of stimulated emission (SE) as a laser component in 1917. But it wasn’t until 1960 that we got the first functional laser. In 1962, Dr. Robert Hail, an American engineer, created the semiconductor laser, which is still in use today.

When it comes to lasers, we’re dealing with quantum realm theory. The theory explains how these devices operate. A flash tube is surrounded by synthetic Ruby. Photons are pushed into the Ruby, forcing them to interact with electrons. The electrons then absorb the photon energy, a process known as stimulated absorption. It will raise electrons to a higher energy state.

In this state, the electron can be concealed again with another photon, causing it to emit an energy photon with the same wavelength, phase, and polarization as the existing incoming photon. This process is known as stimulated emission (SE).

The amplification comes next. Reflective materials are utilized to boost photons, resulting in increased stimulated emission and producing coherent light. Light waves are in phase and move in the same direction as they exit the laser in a narrow light beam.

A semiconductor laser is made up of three components. The P-type conductor is positive, the N-type is negative, and the PN junction lies in the center. Electrons and holes begin to mix in the middle when current passes through the diode. The electron then emits energy in the form of photons through SE. While being reflected off the mirrored surfaces, a chain reaction created more photons. The coherent light is then directed to shine through in a focused beam.

Because the coherent light is mainly at the same frequency, a very thin monochromatic line, usually red or green, is emitted. The wavelength of a red laser is 650 nanometers, while the wavelength of a green one is just 532 nanometers.

Types and Varieties to Choose From

Depending on the job or application, each type emits its lasers differently and has proved to be an excellent tool.


It is termed rotary because it produces a line in a rotating manner across the entire space. It is usually placed in the center of the work area. After calibrating, the spinning head allows the single diode to provide a 360-degree level line. The diode generates a 360-degree rotating beam of light for a horizontal or vertical plane.

This type is often bigger, which is why it is typically installed on solid surveying tripods. When utilized for projects on a vertical plane, some can be put over its side with an optional trivet for better safety. However, once you’ve found a level surface for your tool, you may use its standing leg to move over to where you want your final grade to be.


  • Manually-leveling – with mounted bubble that gives you an understanding of how far off you are.
  • Electronic – uses a pendulum system
  • Automatic leveling (AM) – comes with electronics and that makes it easier for you to get the right results.

Line laser

Transit Tool

The purpose of transit laser levels is to assess the elevation difference between two sites separated by a given distance. These responsive and precise field instruments are easy to set up and can be utilized in any outdoor weather condition that you can bear.

While other versions establish a level line when attached to a tripod, transit levels establish a plumb level through the scope or sight in addition to a line. A full 360-degree circle mark on the base also allows you to move the view around the tripod, which is excellent for surveying.

When set up on a tripod, it shows a level line as you look through them. It would be best to position the tool in the center of your worksite so that you don’t run out of range. It has a limited range, so if you go too far, you will come up short. Install it a little higher so it doesn’t run into the dirt on lower grounds.

When it spins, it either sends out a beam to level both accesses or sends out a perfectly level beam, and the receiver beeps when it reaches the correct angle. In general, the tool will assist you in determining your elevation needs.


The technology of 360-degree lenses became popular in the market a few years ago. Its purpose is to create 360-degree continuous lines. Manufacturers are now seeing the best results by adding self-leveling lasers with 360-degree technology. The horizontal line would be 360 degrees, with the vertical relying on a visor.


It is a multi-line device with one horizontal and one vertical line meeting to frame a divider cross. Some produce more than one cross based on the number of vertical lines and the same flat. It is suitable for ceiling and flooring applications. The more lines there are, the more expensive the unit.

Indoors are generally utilized as visible horizontal and vertical lines to install various fixtures such as bathroom and kitchen fittings, electrical fit-outs, tiling, etc. A few versions can utilize an electronic receiver or detector with pulse properties, beneficial for outdoor use.


A level capable of shooting many horizontal and vertical lines from one end to another across a distance of 65 to 100 feet utilizing LEDs. It features plumb up and plumbs down features, making it ideal for interior application. Few versions include pulsating light innovation with a light detector making them perfect for outdoors and indoors with a dazzling brightness.

It is usually a tiny hand-held device that produces a single line in one direction onto a single wall or workpiece. It can be on virtually any surface that allows it.

For Excavation

Since the development of the machine-mount laser, getting the work done at the construction site has never been easier.

The most annoying part of being a digger driver is getting off the machine to check the level with the rod and then return for a little more digging. Fortunately, machine mountable detectors or excavator lasers save you from jumping out and in of the cab every few minutes to check if you’re off or not.

A machine-mount detector/receiver is mounted to the excavator’s arm and uses laser signals to find jots and red beams. It also saves money since it removes the need for a second person to hold the pole in the trench. To ensure safe attachment, it employs a heavy-duty rare earth magnet and mounting clamps. It also has a 360-degree rotation to ensure that the signal is received regardless of its orientation. The detector comes with ultra-bright LEDs for unfettered visibility to display the grade reading.

Self-leveling (SL)

Self-leveling, or SL, or pendulum ones, give more improved and higher precision and rapid outcome. It automatically locates and keeps a level within a specific range. Some feature bubble vials, so when you conduct initial leveling, the laser itself will take over and accomplish the precise leveling. In other words, If you are relatively close to the right angle, it will do the work itself.

Take notice; SL and automatic-leveling are two separate things. If you are a beginner, the term is quite conflicting with one another. SL features an inbuilt pendulum that does the work, while electronic servos handle all the work for automatic devices.

3 or 5-point Tool

This type is handy when transferring points from the floor to the ceiling. It’s also known as a point-type, and it can be swiveled when put on a tripod to mark the endpoints of a level line.

What to Look For?

Confused about which one is good or which one is best?  Well, it all comes down to the following factors;

Precision & Accuracy

The most vital factor to consider is its accuracy; it can’t give provide a precise line otherwise. A good unit is accurate at 1/16” per 100 feet, ten times more accurate than spirit level. A diode generates a focused beam across the area to be leveled, resulting in a high degree of precision.

Beam Preference

You have the option of selecting horizontal or vertical, cross-line, or 360-degree. High-end units have 2-3 options but are likely to be costly. Models with lower prices feature either vertical or horizontal beams.

Color is the next factor to consider. Beams can be either red or green. Green beam lasers are usually brighter and more visible.

Manual, Auto, or Self-Level

When you turn on an auto laser, it will automatically provide you with a correct level line. It will also completely stop if it is interrupted.

Manual ones require an appropriate setup or the quality of the line generated may drop. They’re best suited for smaller projects.

A pendulum in SL systems quickly adjusts for uneven surfaces—a more exact and accurate method for all types of applications.

How to Use Different Types (Tips & Tricks)

TIP #1: Put on the special laser-enhancement glasses first, the same way you would put on welding glasses when you’re welding or doing oxy acetylene cutting. Lasers are harder to identify in bright light.

TIP #2: When laying up point types, start on the floor and work your way up to the ceiling box or lighting fixture by transferring the points with the laser.

TIP #3: A laser level square is suitable for applications needing square layout lines, as it projects a perpendicular line like crosshairs. Place it on the floor and take measurements from the lines to see how the arrangement will appear.

TIP #4: Use a tripod to adjust the entire setup to the optimal height easily and level it on uneven surfaces.

TIP #5: Locate the studs and mark their center with a unit that projects a plumb line. After that, line up the beam with a stud mark and screw it to the line.

TIP #6: Make a reference line. Measure up or down from the line and mark the wall to get the beam lined up precisely where you want the line to be.

Green vs Red Beamlines

The color difference is pretty noticeable, but aside from that, there are other significant differences between green and red lasers.

Green Red
Brighter to the human eye Not very effective for outdoors
Produce crisper point or line In the distance, the thin red line turns dull.
Price is higher Save money on the price
Have extended range Hardly visible in far distant
