Two new laser pulse energy sensors from Coherent are specifically designed for use with very high energy/peak power lasers operating at low repetition, such as those based on Nd:Yag, ruby, and Ho:Yag
The first of these EnergyMax sensors is a 50mm diameter Yag/Harmonics detector that can operate at 1064nm, 532nm, 355nm and 266nm without the need to change diffusers or any other accessories.
The second is an IR sensor with a 25mm diameter that can work throughout the 694nm to 2.1um wavelength range without any reconfiguration.
Both sensors enable pulse energy measurements from 1.5mJ to 3J, and are intended for repetition rates of less than 50Hz.
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, FieldMaxII Top, 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.
Coherent's EnergyMax sensors measure pulses up to 3J
