How To Chop Diode Laser Beams Electrically At High Speed With Low Noise It is often necessary to have an understanding of how to chop a laser beam. Chopping diode lasers electrically is actually less costly and much simpler than doing so mechanically. This white paper walks through the process of chopping a diode laser beam at high speeds and low noise.  Continue Reading...

University Research Team Faces Challenges Of Measuring Multiple Lasers There are often times where several laser sources must be tested, validated, or qualified for a particular project. Unfortunately, by the time scientists realize that these measurements need to be made, the laser systems are typically already in place, the experiments are ready to be conducted, and any delays could be counterproductive. Therefore, laser measurement equipment needs to be cost effective, commercially available, easy to use, quick...  Continue Reading...
High Power Industrial Laser Applications: New Solutions To Old Problems
High Power Industrial Laser Applications: New Solutions To Old Problems High power laser systems are making their way into more and more industrial applications in order to produce results not previously practical. The advanced scalability, high beam quality, and wall-plug efficiency of fiber lasers in particular have made laser beams with powers of many tens of KW a common tool available for commercial use. Even processes requiring more modest power levels often use a high-power laser system and distribute the beam ...  Continue Reading...
Solving A Difficult Military Beam Alignment Task
Solving A Difficult Military Beam Alignment Task Advances in laser technologies have increased the use of lasers in military systems. One such example is the use of a laser system in the periscope of a nuclear-powered submarine. It is essential to provide instrumentation on-board a 6900 ton submarine that offers accurate pitch, yaw, and roll data. As a result of the critical nature of this information, the burden is then placed on the quality of the laser beam, its size, its shape, and its...  Continue Reading...
