本文叙述了连续单模染料激光在外腔谐振中增强的原理,外腔的构成,介绍了外谐振腔在无多普勒光谱测量中的应用,特别在单模连续染料激光倍频中,应用这种外谐振腔使倍频转换效率提高百余倍。

The paper reports the enhanced mechanism of a dye laser in an external resonant cavity and its construction. The applications of an external resonant cavity in Doppler-free speotroscopic measurement and in frequency doubling of a single-mode CW dye laser are introduced. We achieved a conversion efficiency of frequency doubling over 100 times the original level by using the cavity.
