Measure high pulse energies without water-cooling

Ephraim Greenfield, CTO, Ophir Photonics, commented: "With the advent of higher power lasers across a broad range of applications, there is a need to measure power and energy without requiring large, often cumbersome, water-cooled devices. Today's lasers can be switched on and off precisely, delivering a rectangular pulse of energy. Our new, compact non-water cooled laser sensors use these short pulses of 0.1 to 1s to make laser power measurements up to 8,000W or higher."

The L40(150)A and L50(150)A are general purpose, convection/ballistic-cooled laser power/energy sensors that measure laser power from 0.1 to 150W and laser energy from 0.1 to 4,000J; up to 8,000J with a pulse of 0.5s. Each sensor features a large 50mm aperture and broad spectral response of 0.19-20µm.

The L40(150)A-LP1 is a convection/ballistic-cooled laser sensor. The LP1 coating has a much higher damage threshold for continuous power and more than 1ms pulse measurements. It measures laser power from 0.1 to 150W and energy from 0.1 to 4,000J; up to 8,000J with a pulse of 0.5s. The sensor has a large 50mm aperture and spectral range of 0.25-2.2µm.

The L30C-LP1-26-SH is a conduction-cooled laser sensor with a high damage threshold LP1 coating for measuring high pulse energy and intermittent power. The sensor measures up to 10W of continuous power (100W for two minutes) and energy to 2,000J; up to 4,000J with a pulse of 0.5s. It features a spectral response of 0.25-2.2µm.

The L40(150)A, L40(150)A-LP1, L50(150)A and L30C-LP1-26-SH are available now. OEM pricing is available on request.
