Ophir Photonics Announces Laser Sensors That Measure High Laser Powers Without Water Cooling

Ophir Photonics Group, global leader in precision laser measurement equipment and a Newport Corporation company, today announced four new thermal laser sensors designed for measuring high pulse energies without the need for large, water-cooled devices. Designed for use with high powered lasers, the L40(150)A, L40(150)A-LP1, L50(150)A, and L30C-LP1-26-SH are compact sensors that measure high laser energies up to 8000J. The high power laser irradiates the sensor for a short time, from 0.1 to 1s, and the energy of the pulse is used to calculate laser power.

 

"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," said Ephraim Greenfield, CTO of Ophir Photonics Group. "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 1 sec to make laser power measurements up to 8000W 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 100mW – 150W and laser energy from 100mJ – 4000J; up to 8000J with a pulse of 0.5sec. 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 long >1ms pulse measurements. It measures laser power from 100mW – 150W and energy from 100mJ – 4000J; up to or 8000J with a pulse of 0.5sec. The sensor has a large 50mm aperture and spectral range of 0.25 – 2.2µm, and 2.94µm.

 

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 2000J; up to 4000J with a pulse of 0.5sec. It features a spectral response of 0.25 – 2.2µm.
