摘　　要：综述了使用半导体泵浦的固体环型激光器的优点———可以使激光陀螺实现全固体化、提高光束质量并减小陀螺的锁区 ,但是由于半导体泵浦的固体环型激光器工作于多纵模状态 ,对陀螺的精度有很大影响。介绍了可以实现固体环型激光器单纵模的方法 ,即色散法、F P干涉法、复合腔法等 ,并对国内外最近出现的实现单纵模的方法进行了总结和比较。得出F P干涉法是最直接有效的方法 ,其它方法可以进一步在固体环型激光器中验证。In the paper,the merits of laser diode pumped solid state ring laser are introduced. The gyroscope can be made in solid state,the quality of the beam can be improved and the dead lock can be reduced . But because of the multi longitudinal mode the precision of the gyroscope is decreased. Methods of longitudinal mode selection are discussed. Meantime thes e methods are compared,dispersion,F P etalon,composite cavity etc. The con clusion is that F P etalon is the most effective method to realize the single longitudinal mode and others will be validated in the experiments.
