Model PM1K

These water-cooled sensors are used to measure lasers over 300W average

power output. They are excellent choices for measuring CO

and Nd:YAG

lasers. Larger-area versions are available on the next page.

Tap or distilled cooling water is recommended with these sensors – DI

water can not be used. Flow rates are power dependent and range from

0.5 to 4 gallons per minute; pressure depends upon ow rate and ranges

from 3 to 40 PSI (visit product pages at www.Coherent.com/LMC for more

technical details).

Device

Specications

Intermittent power levels may be sustainable for longer than 5 minutes when used with lasers with large diameter, non-Gaussian beam proles.

Monitor closely for coating damage if used longer than ve minutes at higher powers.

The damage resistance of the coating is dependent upon the beam size and prole, the average power level, and the water ow rate.
