摘　　要：铒玻璃激光器可以直接输出1.54μm人眼安全激光,主要应用在激光测距。报道了LD侧面抽运的Er+3,Yb+3共掺磷酸盐玻璃激光器的运转。实现了自由振荡输出60m J;在0.5Hz重复频率下,稳定输出50m J/脉冲,波长1.54μm。实验表明,抽运的对称性和均匀性是设计铒玻璃激光器的关键。Erbium glass lasers can directly output 1.54μm eye-safe laser and can be used in eye-safe rangefinding applications. LD bar side-pumped Er^＋3 ,Yb^＋3 phosphate glass laser is reported. At free-running mode maximum pulse energy of 60mJ is obtained. At 0.5Hz repetition rate,it can output 50mJ/pulse,at 1.54μm stably. Eexperiments indicate that the key of Er glass laser design is pumping symmetry and uniformity.
