Ophir Photonics has introduced a new line of 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 the typical glass or ceramic substrate. This means the PF Sensors provide significantly higher power handling capacity and faster response times. They can handle up to 20x the power density, up to 3KW/cm2, and the response rate time is as fast as 1s.
