前言用 NdLaPP 激光晶体作工作物质的激光器,有阈值低,效率高,体积小及价格便宜等优点。用它做成的小型激光器,已有广泛的应用。由于 NdLaPP 晶体受外力后易损坏,所以直接用水冷却激光器内的晶棒是十分困难的。又因 NdLaPP 晶体导热性能较差,所以也难以用它做成高重复率激光器或激光放大器。但我们用 NdLaPP 作工作物质研制成的低重复率激光器和激光放大器却得到了较好的结果。本文报道对用普通脉冲氙灯研 Preface NdLaPP laser crystal for the working substance of the laser, a low threshold, high efficiency, small size and low price and so on. Small laser made of it has been widely used. Since NdLaPP crystal is easily damaged by external force, it is very difficult to directly cool the ingot in the laser with water. NdLaPP crystal due to poor thermal conductivity, it is also difficult to use it made of high repetition rate laser or laser amplifier. However, the low repetition rate lasers and laser amplifiers we developed using NdLaPP as a working substance gave better results. This article reports the use of ordinary pulsed xenon lamp research
