OPHIR Photonics Introduces New, Highest Damage Threshold Coating for High Power Laser Sensors

Press release date: January 27, 2014

North Logan, Utah - Ophir Photonics, global leader in precision laser measurement equipment and a Newport Corporation brand, today announced the addition of a more damage resistant coating to the company's high power laser sensors in the 300W to 1500W range. The L300W-LP, FL400A-LP, 1000W-LP, and L1500W-LP sensors now feature the improved LP1 absorber. Designed for continuous power and long >1ms pulses, this coating provides a damage threshold up to 2X higher than competitive models.

"The LP1 absorber coating provides Ophir's high power laser sensors with the highest damage thresholds in the industry," said Ephraim Greenfield, CTO, Ophir Photonics. "Traditional surface absorbers have a much lower damage threshold at >1000W. They can damage at 2-3 kW/cm2. We have developed a denser coating that has higher heat resistance, thus improving the damage threshold for our high power lasers. The LP1 coating also has a much higher damage threshold for long pulses reaching power damage thresholds of over 200 J/cm2 for 10 ms pulses."

The LP1 absorber coating is now available on the following high power, large aperture laser sensors:
- L300W-LP1-50, high power water-cooled thermal sensor for 4W – 300W, 50mm aperture,
- FL400A-LP1-50, medium-high power fan-cooled thermal sensor for 300mW–400W, 50mm aperture,
- 1000W-LP1-34, high power water-cooled thermal sensor for 5W – 1000W, 34mm aperture,
- L1500W-LP1-50, high power water-cooled thermal sensor for 15W – 1500W, 50mm aperture,

The LP1 absorber coating is available now on the L300W-LP1-50, FL400A-LP1-50, 1000W-LP1-34, and L1500W-LP1-50.
