A volume-absorbing head for use with high-energy pulsed lasers is available from Ophir Optronics Inc. The Model 30(150)A-HE-DIF detector head provides average continuous or intermittent power measurements up to 30 W and 150 W, respectively. The energy density rating is 5 J/cm2 at 1064 nm, which is achieved using a diffuser-in/diffuser-out technique that spreads the concentrated pulsed beam. The loss through the diffuser is stored in the EEROM of the connector. The device also offers a maximum power density of 500 W/cm2.
