摘要
利用XeF2光解离波图像，测量了现有激光实验条件下的解离波半径及传输速度，解离波厚度为5～8mm，传输速度随泵浦时间的增加而减慢，平均速度约13km／s。选择四种不同的腔轴位置，腔轴距泵浦源表面的距离d分别为10、13、16、20mm，激光实验结果表明，XeF2光解离波的空间传输对XeF（C—A）激光的形成有影响，激光形成时间、脉宽均随腔轴远离泵浦源而增加；输出能量在腔轴取13mm处最大。
The curves of the radius and transmitted velocity of the XeF2 photodissociation wave （PDW） with time have been obtained by measuring the framing photographs of the PDW. The thickness of the PDW is 5-8mm with the average transmitted velocity of 13km/s and the velocity decreases with increasing the pumping time. The laser experiments are operated in the case of the distance d between the optical axis of laser and the source surface is 10mm, 13mm, 16mm, 20mm,respectively. The experimental results show that the position of laser axis affects the lasing formed time, pulse duration and output energy. The lasing formed time and the pulse duration of the laser all increase with the increasing d and the maximum output energy is obtained when d = 13mm.
