Paper Abstract

Output pulse energy of 300 J for a pulse duration of i-I .5 ns has been achieved in a six-stage neodymium phosphate glass amplifier. A multistage spatial filter based on an pin hole line provides an aperture filling factor of 0.8 at the laser output. As a result, stored energy has efficiently been extracted, and power elements of the system have been accommodated on a single optical table. The energy efficiency of radiation conversion to the second harmonic is 55%. The laser is synchronized with a cw femtosecond laser with accuracy 50 ns and is intended for pumping of a chirped-pulse optical parametric amplifier.
