Co2 Laser Beam Width

These lasers can maintain continuous and very high levels of power and are typically used in cutting welding etching and marking applications.

Co2 laser beam width.

If you have the camera option then look at the target on your computer. The divergence of a laser beam can be calculated if the beam diameter d 1 and d 2 at two separate distances are known. When a laser beam propagates along its optical path its diameter is continually changing. Where w 0 is the beam waist the smallest radius of the gaussian beam and z r is the rayleigh length.

Note that in the example we chose znse as our lens material and meniscus as its shape good for co 2. Turn on the co2 laser and adjust the laser power so that the laser beam is visible and not too bright on the side viewport. If we consider the ideal case of a gaussian beam the beam width or radius w along the propagation axis z is defined by the following equation. Things have changed however with the introduction of spiricon s new beamwatch which measures laser beam width and focal length of any laser beam without attenuation.

How to make laser beam alignment. Usually divergence angle is taken as the full angle of opening of the beam. This video teaches you how to adjust the laser beam. It was invented by kumar patel of bell labs in 1964 and is still one of the most useful.

But to maximize the power and clarity of your laser cutting and engraving the laser beam spot size has to be clean small and as round as the laws of physics will allow. Carbon dioxide co 2 lasers use the energy state transitions between vibrational and rotational states of co 2 molecules to emit at long ir about 10 µm wavelengths. Carbon dioxide lasers are the highest power continuous wave lasers that are currently available. The power density of a tightly focused industrial laser can be quite high.

The co2 laser produces a beam of infrared light with the principal wavelength bands centering on 9 6 and 10 6 micrometers. They are also quite efficient. Examine the location of the raw co2 laser beam in relation to the cross hairs. The ratio of output power to pump power can be as large as 20.

The wavelength for a co2 laser beam is roughly 10 microns or 01mm. This probably seems too good to be true. Insert the mahoney beam visualization tool into the first beam bender. Laser tubes producing an out of round or oval shaped beam will degrade the cutting and engraving quality substantially.

The carbon dioxide laser was one of the earliest gas lasers to be developed.
