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...
