Paper Abstract

A MOPA Nd:YAG laser source incorporating a SBS phase-conjugate mirror delivering 12 ns long 1,6X diffraction-limited pulses at a pumping rate of 10 Hz is experimentally demonstrated. High reflectivity (70-80%) of phase conjugate mirrors using CCIF3 gas near its critical point and CH4 gas with single laser shots is reported. Fidelity of phase conjugation stays high (0.8) with broadband radiation (0.7 cm-1). Output MOPA energies and beam quality are measured as a function of oscillator output energy and amplifier flashlamp pumping level. Advanced beam steering performed with this phase-conjugate laser design is presented.
