着重研究了双光束拉曼组束改善准分子激光光束质量。通过理论计算得出，在畸变泵浦光作用下可以获得近衍射极限Ｓｔｏｋｅｓ光的放大。并在稳态和瞬态激光脉冲的条件下，讨论了Ｒａｍａｎ工作介质的选择。在此基础上进行了氯化氙准分子激光在氢气中的双光束Ｒａｍａｎ组束实验研究，近衍射极限Ｓｔｏｋｅｓ光在获得功率放大的同时，其远场分布保持不变。激光聚焦亮度提高约３０００倍。最后讨论了放大自发辐射的抑制。
Focusing on the double beam Raman beam to improve the quality of the excimer laser beam. The theoretical calculation shows that the near-diffraction limit Stokes light can be amplified under the action of distorted pump light. Under the condition of steady state and transient laser pulse, the choice of working medium of Raman is discussed. On this basis, the Raman beam experiment of two beams of xenon chloride excimer laser in hydrogen was carried out. The far-field distribution of near-diffraction limited Stokes light was constant while the power was amplified. Laser focus brightness increased by about 3000 times. Finally, the suppression of spontaneous emission amplification is discussed.
