Coherent PowerMax-USB PM150-50C Power Sensor Description：

Datasheet 1 Datasheet 2 User's Manual

This PowerMax-USB PM150-50C sensor is a water-cooled laser power sensor intended for measuring lasers up to 150W with water, and up to 80W without water for short durations (up to five minutes at a time). This sensor model is also very commonly used for individual long-pulse energy measurements up to 150J.

The sensor is terminated in a USB cable that interfaces directly to a PC. A DB25 model (PN 1098412) is available.

Water-cooled thermopile sensor for measuring pulsed & CW lasers between 300 mW and 150W. It can be used to measure 80W without water, intermittently, for up to five minutes. Direct USB interface.
