High-power laser sensors

North Logan, UT - Ophir Photonics Group has debuted high-power laser sensors and scatter shield accessories for measuring large and divergent laser sources, such as diode stacks and arrays.

The 6000W-BB-200x200 and L2000W-BB-120 are water-cooled laser sensors for measuring the power and energy of very large, high-power laser beams. Both have broad spectral response from 0.19 to 20µm. The L2000W-BB-120 includes a "Smart Connector" interface that operates with the company's StarLite, Nova II, and Vega smart displays, and Juno PC interface. It can also be directly connected to a PC via RS232.

The L100(500)A-PF-120 is designed for high-peak-power, high-energy measurements over a 0.15–20µm spectral range. The L100(500)A can measure single-shot energy of high-peak-power, short-pulse lasers at up to 3J/cm². It can also measure high-power lasers for short (~1s) exposures at up to 6000W, and can continuously measure up to 100W (500W with heat sink).

The company's high-power 10K-W and 30K-W laser sensors have high absorbance, but 3–4% of the light is still backscattered. This can heat surrounding surfaces of the sensor. The 10K-W and 30K-W scatter shields reduce this backscatter by about 70%.
