Recent advances and analysis of optical resonators used for high power diode pumped solid-state lasers

In this paper,some novel resonators used for high power diode pumped solid-state lasers in recent years,such as the rod imaging unstable resonator,near concentric unstable resonator and folded resonators,as well as the SBS phase conjugated MOPA system have been analyzed in depth,and the relevant techniques for achieving both high output power and good beam quality have been discussed.
