MKS INSTRUMENTS Ophir F80(120)A-CM-17, a state-of-the-art thermal sensor for measuring high repetition rate lasers with very short pulses in the nano, pico, and femto second ranges. High repetition rate lasers induce damage to conventional sensor coatings at lower power densities than required by users. The compact, calibrated, fan cooled sensor is designed to solve that problem. It can withstand higher power densities and measure average power up to 80W and intermittent power up to 120W. This makes the new device suitable for use in micromachining and material micro-processing applications in the semiconductor, display, and medical industries.
