摘　　要：为了研制一种能在-40℃^+65℃环境下适用于机载吊舱的小型风冷重频二极管抽运Nd∶YAG板条激光器,克服采用热电恒温二极管抽运源的一系列问题,采用了无热电恒温二极管抽运源的方法,并进行了实验验证。结果表明,该激光器能在-40℃^+65℃环境下,以20Hz^30Hz脉冲重复频率稳定可靠的工作,激光输出能量100m J^150m J,激光脉宽6ns^7ns,激光束散角经4倍天线扩束后约1mrad。该激光器能适用于多种机载或车载激光测距/指示仪。In order to develop anew type of airborne compact repetitive diode-pumped slab laser operating at - 40 ℃＋ 65 ℃ , a diode-pumped laser without thermoelectric coolers was adoped to overcome the problems of thermoelectric coolers. Theexperimental results show that the laser can work stably and reliably under the condition of -40℃＋65℃ environmentat20Hz？30Hz pulse repetition frequencies with laser output energy of lOOmJ -150mJ and pulse width of 6ns -7ns. The beam divergencebecomes lmrad after passing through 4 x telescope. The diode-pumped laser can be used in airborne and carborne laserrangefinders/ designators.
