摘要
介绍了一种仅用镇模Nd：YAG振荡器进行的卫星激光测距实验。此类振荡器的倍频输出可达5～10mJ（532um），脉宽50～100ps。整个振荡器仅未用一支氙灯和一支Nd：YAG棒，体积紧凑、小巧，重量仅32kg。接收望远镜口径为60cm，单光子雪崩二极管接收器。本系统对8000km远的Lageos－1，Lageos－2两颗卫星进行了成功的测距。
This paper describes the SLR experiment with only a compact Nd =YAG mode - lockedoscillator. The output of the oscillator is 5 ~ 10mJ (532nm), 50~100ps pulsewidth. Onlyone flashlamp and one Nd= YAG rod is adopted, so the laser has a small size with 32 kgweight. The 60cm aperture receiving telescope and the single photon avalanche diode(SPAD) detector is used. The successive ranging to Lageos - 1 and Lageos - 2 (about8000km range) on October 31 and November 1, 1994 are reported (Fig. 1, 2, 3 and 4).
