OSTI ID:7142357
The efforts on a 10 month program are described whose objective was the design, development and delivery of a mode-locked internally frequency doubled Nd:YAG laser operating at 500 MHz PRF with an average output power of 250 MW at 0.53 micrometers or 1.0W at 1.06 micrometers (TEM (sub 00) mode) with a pulse width of less than 300 PS (measured at 10% amplitude points). The approach utilized a 4 mm bore diameter, protected end seal potassium-rubidium (K-Rb) lamp as a pump source in a cold mirror pump cavity conductively cooled with heat pipes. A three mirror L shaped resonator was used to allow efficient coherent combination of the two green beams generated in a 5 mm cube barium-sodium-niobate (BSN) crystal.
