New Ophir® Laser Power Sensor Measures High Repetition Rate, Short Pulse Industrial Lasers for Micomachining up to 120W

MKS Instruments, Inc. (NASDAQ: MKSI), a global provider of technologies that enable advanced processes and improve productivity, has announced the Ophir® F80(120)A-CM-17, a state-of-the-art thermal sensor for measuring high repetition rate lasers with very short pulses in the nano, pico, and femtosecond ranges. High repetition rate lasers induce damage to conventional sensor coatings at lower power densities than required by users. The F80(120)A-CM-17 is a compact, calibrated, fan-cooled sensor designed to solve that problem. It can withstand higher power densities and measure average power up to 80W and intermittent power up to 120W. This makes the new sensor ideal for use in micromachining and material micro-processing applications in the semiconductor, display, and medical industries.

The Ophir F80(120)A-CM-17 laser power sensor works with industrial lasers at wavelengths from 248nm – 9.4µm. It measures laser power from 100mW to 80W continuous (to 120W intermittent). The sensor is fan-cooled with a 17.5mm aperture. It features a unique absorber that will not suffer from the ablation usually caused by very short pulses and can withstand high power densities up to 7 kW/cm2 at 80W.

"Micromachining demands precise delivery of near-perfect laser beam quality, which depends on lasers with shorter wavelengths, shorter pulses, and high repetition rates with high average power and increased pulse energy," said Reuven Silverman, General Manager, Ophir Photonics. "To rapidly fabricate precisely controlled features requires 24x7 power monitoring, especially for high repetition pulsed lasers with nanosecond pulses. The F80(120)A-CM-17 sensor meets this challenge by providing high accuracy measurements in such circumstances and is able to withstand higher power densities for high repetition rate pulsed lasers than sensors with conventional coatings."

The Ophir F80(120)A-CM-17 sensor, like all Ophir sensors, features a "Smart Connector" interface that operates with the company's Centauri, StarBright, Vega, Nova II, and StarLite smart displays,  Juno and Juno+ compact USB PC interface and EA-1 Ethernet adapter. Users can choose between a variety of data display formats, including Digital with Bargraph, Line Plot, Pulse Chart, and Real Time Statistics. The displays also feature sophisticated logging of power and energy, statistics, histograms, and more, as well as advanced math functions. The display is automatically configured and calibrated when plugged into one of the company's laser measurement heads.
