Energy Sensors for High Peak Power Lasers from Coherent

Two new laser pulse energy sensors from Coherent, Inc. are specifically designed for use with very high energy/peak power lasers operating at low repetition rates, such as those based on Nd:YAG, Ruby and Ho:YAG.

  The first of these EnergyMax sensors is a 50 mm diameter YAG/Harmonics detector that can operate at 1064 nm, 532 nm, 355 nm and 266 nm without the need to change diffusers or any other accessories.  The second is an IR sensor with a 25 mm diameter that can work throughout the 694 nm to 2.1 µm wavelength range without any reconfiguration.  Both sensors enable pulse energy measurements from 1.5 mJ to 3J, and are intended for repetition rates of less than 50 Hz.

Sensor performance can be further extended with an optional heatsink, which can be easily attached by the user to increase the maximum energy or average power range.  In addition, all EnergyMax sensors are now configured as "smart" devices that incorporate onboard electronics to automatically correct for ambient temperature, as well as built-in wavelength compensation factors.  They provide plug and play compatibility with several Coherent meters (3sigma, FieldMaxIITOP, FieldMaxII-P, EPM1000 and EPM2000 meters) that range from handheld units, suitable for field service personnel, to laboratory instruments that feature a wide range of statistical analysis and data logging capabilities.
