【摘要】 为了提高灯泵钛宝石激光器的输出能量和效率，对灯泵钛宝石激光器进行了大量的试验研究工作。对国产氙灯进行了快速放电和寿命试验；测得了在不同放电电流密度情况下的氙灯发光光谱分布；试验采用双灯串接泵浦，双棱镜色散光学谐振腔，平平腔型，调谐范围为７５０～９５０ｎｍ，在中心波长８００ｎｍ处得到激光输出能量为８９３ｍＪ，电光转换效率为０．８９％。该激光器的阈值约为１５Ｊ。更多还原

【Abstract】 A lot of work has been done to improve the output energy and the efficiency of flash lamp pumped Ti:sapphire laser. The lifetime and the fast pulse discharging performance of domestic xenon flash lamp have been researched. The spectrum of xenon flash lamp in different discharging current are tested. Two xenon flash lamps are connected in series in the experiment, and the flat flat resonator is dispersed by double prisms. Tunable range from 750nm to 950nm, laser output 893 mJ (800nm), electro optic efficiency 0 89%. The pump threshold of the laser is estimated 15J with the help of the illustration of input energy vs output energy.更多还原
