Measure high laser powers without water cooling

Laser irradiates the sensor for a short time, from 0.1 to 1 s, and the energy of the pulse is used to calculate the power.


Measure energies up to 8,000 J.

Measure energies up to 8,000 J.

Ophir Photonics Group has four new thermal laser sensors that measure high-pulse energies, but without large, water-cooled devices.

The compact sensors measure energies up to 8,000 J. The laser irradiates the sensor for a short time, from 0.1 to 1 s, and the energy of the pulse is used to calculate the power.

The L40(150)A and L50(150)A measure from 100 mW to 150 W and laser energy from 100 mJ to 4,000 J; and up to 8,000 J with a pulse of 0.5 sec. Each sensor has a large 50-mm aperture and broad spectral response of 0.19 to 20 µm.

The L40(150)A-LP1 measures laser power from 100 mW to 150 W and energy from 100 mJ to 4,000 J; and up to or 8,000 J with a pulse of 0.5 sec. The sensor has a large 50-mm aperture and spectral range of 0.25 to 2.2 µm, and 2.94 µm.

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 10 W of continuous power (100 W for two minutes) and energy to 2,000 J; up to 4,000 J with a pulse of 0.5 sec. It features a spectral response of 0.25 to 2.2 µm.

Ophir Photonics is a provider of instrumentation based in North Logan, Utah.
