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100mJ～150mJ, 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 a new 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. The experimental results show that the laser can work stably and reliably under the condition of -40℃~+65℃ environment at 20Hz~30Hz pulse repetition frequencies with laser output energy of 100mJ～150mJ and pulse width of 6ns～7ns. The beam divergence becomes 1mrad after passing through 4×telescope. The diode-pumped laser can be used in airborne and carborne laser rangefinders/designators.
