New laser energy sensor measures pulses down to 100 nJ

Coherent J 10MT Laser Energy Sensor (PresseBox) (Santa Clara, Calif., ) The newest addition to the Coherent Inc. (Santa Clara, CA) (Nasdaq: COHR) EnergyMax series of laser energy sensors enables measurement of very low energy pulses - down to the 100 nJ level. Specifically, the new J-10MT-10KHZ delivers a single-pulse noise equivalent energy level of 10 nJ on 100 nJ pulses (i.e., without averaging), and can operate at repetition rates as high as 10 kHz. The J-10MT-10KHZ utilizes the same novel, diffuse metallic coating as other High Repetition Rate EnergyMax Series Sensors, which incorporates automatic spectral compensation over 193 nm to 2100 nm. The 10 mm diameter sensor is plug and play compatible with Coherent's LabMax, 3sigma, EPM1000 and EPM2000 meters, thus offering a wide variety of measurement options in terms of capabilities and cost. Sensor reliability is enhanced by a three meter long molded cable with bend and strain relief which protects the unit against rough handling.

The rugged and reliable J-10MT-10KHZ is suitable for a wide variety of measurement tasks in both the research and manufacturing environments.
