360-W, 1-kHz pulse generation from a diode-pumped Nd:YAG amplifier with a phase conjugation mirror

For the pumping of a high-average-power ultrashort-pulse Ti:sapphire chirped-pulse-amplification (CPA) laser systems, a high-average-power (LD) pumped Nd:YAG laser master-oscillator-power-amplifier (MOPA) system has been developed. It has high efficiency, a correspondingly small thermal load, and is also extremely compact as compared to the lamp pumped laser system. It is applicable and scalable to the design of high-powered laser system. The details of the design and performance of this system will be presented.
