无(腔)镜系统的相干幅射

Coherent Emission of a Mirrorless System

介绍用行波泵浦染料激光的实验和理论研究。提出获得无（腔）镜系统相干幅射的判据:（1）纵横比D/L】1/500,（2）波长相对孔径D/λ≮10;（3）前向增益G=eσN·L】

Some experimental and theoritical studies on traveling pump dye laser arc presented. For realigation the coherent emited, three criterions should be satisfied:(1)Aspect D/L>1/500; (2)Ratio of aperture to wavelength D/λ≮ 10;(3)Advance gain G=e~σN L≥1000.
