Laser Beam Profile Picture

In this project we learned not only about the changing profile and propagation of a laser beam we also discovered how to determine the length and mirror configuration of the laser cavity.

Laser beam profile picture.

Top row shows an industrial nd yag laser exhibiting a gaussian beam left which gives rise to a multi peaked distribution following an increase in power of 1 7 times. M2 is a measure of how close a laser beam s intensity profile is to a perfect gaussian distribution. Download laser beam stock pictures and images in the best photography agency reasonable prices millions of high quality and royalty free stock photos and images. Finally we learned that careful measurements of the beam profile such as ours can even be used to roughly determine.

Find the perfect laser beam stock photo. By using a commercially available ccd camera or cmos camera an extremely low cost and practical beam measurement system can be easily constructed. 87902224 red laser beams light effect on black background photo. 42638679 red laser beam ray icon for apps and websites.

Well aligned co 2 laser cavity. Once the laser was tuned to the beam profile of figure 6b it gave consistent results in scribing the ceramic. These can be interpolated to produce a 2d image but it won t necessarily be the true picture of your laser. Bottom row shows a co 2 laser profile before left and after cavity alignment right.

A picture of the setup. If it were a perfect gaussian beam then m2 1. Depending on the application and industry m2 values of 1 1 1 2 and even up to 1 5 may be considered high quality tem00 beams. Laser beam profile measurement methods 3 1 non electronic methods there are a number of non electronic methods of laser beam profile measurement.

Actually there are two slits so it makes two 1d profiles an x axis and y axis. Beam profiler with m2 platform software laseview beam profiler with m2 platform software laseview is a highly functional and versatile laser beam profiler software that can use a commercially available ccd camera as a beam profiler. Scanning slit profilers use a clever mechanism to take tiny samples of the laser beam through its narrow slit. A laser beam profiler captures displays and records the spatial intensity profile of a laser beam at a particular plane transverse to the beam propagation path.

This produces a one dimensional profile.
