Original Press Release:

New Thermal Absorber Head Designed with High Damage Threshold for Higher Energy Q Switched YAG Lasers

Danvers, MA January 2003. To meet the need of high energy pulsed lasers, Ophir Optronics, Inc. announces the release of a new high performance Volume Absorbing head. The Model 30(150)A-HE-DIF detector head is designed specifically for high energy output measurements from the newest high power Q switched YAG lasers.

The Model 30(150)A-HE-DIF head offers average power measurements up to 30 Watts of continuous or up to 150 Watts of intermittent measurement capability. The energy density rating is 5J/cm² for 1064nm. These high ratings are obtained by using a "Diffuser IN" and "Diffuser Out" technique to spread out the concentrated pulsed beam. The loss through the diffuser is stored in the EEROM of the connector. The maximum average power density is 500W/cm². In addition, the Model 30(150)A-HE- DIFF offers three digital power scales: 3W, 30W and 150W, and a response time under 4 seconds. The head information is stored in the EEROM of the absorber head and is downloaded when the display is attached and turned on, making all heads plug-and-play ready. The head is compatible with all the Ophir, Laserstar series displays as well as a USB interface box that allows users to connect the head directly to their PC.
