Featuring 34 mm aperture, Model 1000WP-BB-34 measures powers from 5–1,000 W and energy from 400 mJ to 300 J. Water-cooled thermal sensor provides damage threshold of 6 kW/cm² at full power and 2.5 s response time. Broadband absorbers can measure spectral range from 190 nm to 20 µm. Since all materials that come in contact with cooling water are either copper or non-metallic, possibility of contaminating water or corroding sensor is eliminated.
