Characteristics and performance of high-power CW krypton arc lamps for Nd:YAG laser pumping

Experimental results are presented on the performance of CW krypton arc lamps operated at power levels up to 20 kW. These lamps are suitable for pumping of high-powered Nd:YAG lasers. Operating life and electrical and spectral characteristics of the lamps were tested as a function of arc length, bore size, and fill pressure.
