Abstract
Although there are several types of detectors useful in the ultraviolet (uv), few have subnanosecond response time with large detector area. Krypton fluoride and other pulsed uv lasers have pulse capabilities ranging from less than 100 ps to 30 ns. For these lasers, the energy/pulse can range from nanojoules (in 100 ps) to joules (in 10 ns). Strontium barium niobate (SBN) pyroelectric detectors have been developed for infrared (ir) usage under similar pulse conditions. This material is absorptive below 400 nm. Design of appropriate detectors for the uv requires (primarily) characterization of the uv and vacuum ul-traviolet (vuv) pulse damage threshold, and examination of the surface preparation tech-niques. Large-area detectors are desirable because uv radiation can be difficult to focus and uv beams can be nonuniform. Los Alamos has developed sub-one-hundred-ps detectors up to 0.1 cm2 and subnanosecond detectors 1 cm2 in the area for the ir. These designs are being adapted to the uv. Results of this program are reported.
