摘　　要：（一）无腔染料激光器 一、引言 不使用共振腔便能得到强受激发射的光通称为放大自发辐射NIASE，一般也叫超辐射或超荧光。它是自发辐射在已形成粒子数反转分布的高增益激活介质中沿激活区轴向传播时通过感应发射过程依次行波放大所产生的。A XeCl excimer laser at 308 nm is used as a transversely pumpingsource for dye solution. 1.The characteristics of-the dye laser without cavity and with one mirror are soudied experimentaly.A simple and effectivc way is provided to generate nanosecond pulse dye laser.The measurements have wavelength at 576.35nm of Rhodamin 6G dye laser without cavity, single pulse energy of 0.14--0.21mJ/pulse, energy conversion efficiencies of 5.7% ,pulse width of ions, all divergence angle of the laser beem of 5 mrads;wavelength at 589.4nm of Rhodamim B dye laser without cavity, pulse width of 8ns spectral linewidth of 0.15A. 2,Tunable output of dye laser at ultraviolet visible range is achieved by using grazing-incidence grating cavity.We have obtained tunable wavelength at 384 .85-400.5 nm for-NPO dye, and-for Rhodamin 6G dye laserat 571.1-800.4nm and for Rhodamin B dye laser at 596.2--643.3nm. The measurements have spectral linewiath of 0.11 A
