Stable continuous-wave passive mode-locking of diode-end-pumped Nd:GdVO_(4) and Nd:YAG lasers with semiconductor saturable absorber mirrors (SESAMs) are reported. The comparative study shows that the Nd:GdVO_(4) crystal is efficient to decrease the Q-switched mode-locking tendency, and easier to continuouswave (CW) mode lock than Nd:YAG.

本文介绍聚全氟乙丙烯包皮的氟锆酸盐(ZrF4-BaF2-LaF3-AlF3-NaF)玻璃光纤的制备方法.研究了各种工艺因素对氟锆酸盐玻璃和光纤散射损耗的影响.结果表明,选择适当的熔化温度和均化时间,玻璃熔化和光纤拉制时环境中低的水含量是制得的损耗氟锆酸盐玻璃光纤的关键;配合料中引入适量NH4HF2,选用温度结构合理的拉丝炉及拉丝工艺也有助于降低光纤的损耗.在此工作基础上,获得了波长2.32μm处损耗为0.24dB/m的氟锆酸盐玻璃光纤.
We discuss the optimal design of line-tapered multimode interference (MMI) devices using a genetic algorithm (GA). A 1×4 MMI device is designed as a numerical example. Compared with the conventional design based on self-imaging theory, the present method

为了在有限的太阳观测窗口内获得高质量的太阳光谱数据,需保证太阳进入观测窗口时仪器已完成自身预热。为保证仪器预热时间的一致性,需在轨实时预报预热开始时刻,需对每轨太阳开始进入仪器观测窗口的时间进行短时间高精度预报。详细介绍了一种由卫星平台当前广播时间和轨道瞬根推导预报时刻太阳角度的方法。利用该方法预报某一太阳同步轨道卫星本体坐标系下的太阳角度,并将预报结果与STK仿真结果进行比对。该预报方法在预热时间内的最大角度误差为0.5°,导致预热时间最大偏差为20 s,满足1 min的指标要求。分析了预报方法中的主要
