无热电恒温的小型重频二极管抽运板条激光器

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。

Compact repetitive diode-pumped slab lasers without thermoelectric coolers

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 .
