Absorber Sensors

Ophir Photonics Group (Logan, UT) has announced high-damage threshold power volume absorbers for short pulsed lasers (<1us). The PF Sensors absorb a laser’s energy in the volume of the material being used. The sensors make use of a spray deposited on the surface, not a glass or ceramic substrate. The absorbers handle up to 20× the power density, up to 3KW/cm2, and the response rate time is as fast as 1s.

The PF Absorber Sensors include four models: 50(150)A-PF-35, for up to 50W continuous and 150W intermittent with a large 35mm aperture; 15(50)A-PF-DIF-18, for 15W continuous and 50W intermittent; 50A-PF-DIF-18, for 50W continuous; and F100A-PF-DIF-18 for 100W continuous.
