Coherent PowerMax-Pro RS 150 HD ‘nano’ Fast Power Sensor Description：

Datasheet User's Manual

This PowerMax-Pro RS 150 HD ‘nano’ sensor incorporates a fast thin-film detector technology that responds in tens of microseconds. This model has a reduced bandwidth intended for measuring nanosecond, picosecond, and femtosecond lasers up to 150W.

The sensor is terminated in an RS232 cable for directly interfacing with a PC or industrial controller. A DB25 model (PN 1325549) is available.

Fast, thin-film transverse thermoelectric, water-cooled power sensor for measuring lasers between 200 mW and 150W. This “nano” model is designed for nanosecond, picosecond, and femtosecond lasers up to 150W. Direct RS232 interface.
