LD Pumped Nd:YAG Microchip Lasers

Compared with diode lasers, LD pumped Nd:YAG microchip lasers, in each of which the Nd:YAG crystal itself forms the resonance cavity, have narrower frequency linewidth, better beam quality and longer coherent length, meanwhile they are remarkably simple and compact. So LD pumped Nd:YAG microchip lasers are promising laser sources to substitute for diode lasers in some measurement fields. Now, researchers focus their attentions on achieving single frequency, single mode continuous output and linear frequency modulation characteristics. In this article, we present a summary on LD pumped Nd:YAG microchip or microcavity lasers, including recent developments, achievements and applications. Especially, we brief some new methods and techniques on frequency modulation of such lasers.
