Laser Beam Measurement
Slit-Based Profilers for Pulsed Beams
Although slit-based profilers were designed to measure continuous-wave (CW) lasers, they can also work for pulsed-mode lasers. Measuring pulsed-beam lasers has generally required the use of a CCD array profiler. This is a reasonable solution for low-power lasers in the UV and visible wavelength range, but these require external attenuation when used with CCD cameras. Once the lasers leave the UV-VIS range, array cameras become extremely expensive. Although low-frequency pulsed lasers...

Belmont Technical College
Belmont Technical College has a number of options available to area industrial firms in the realm of training and assessment. The structure of an Associate Degree in Technical Studies remains the most popular. Another option available is catalog associate degree programs being taught at employees' on-site locations. Belmont Technical College has worked with local industry in developing assessment exams for apprenticeship programs, as well as craft-combination efforts.
