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. A smart sensor interface
