A compact Er:fiber ring laser operated at a fundamental repetition rate of 325 MHz is reported. Two gain fibers with opposite dispersion are employed to shorten the fiber laser cavity for high repetition rate and soliton-like pulse generation without losi
利用新电光材料KTP晶体的有效电光系数γc1,制成电光开关,实验研究了它的热光效应。成功地用它对输出脉宽为50 ns的Nd:YLF单纵模调Q激光削波整形。实验表明,KTP普克尔盒的半波电压低及电容小,配合微带传输线后,能够获得脉宽为1～10 ns,形状几乎任意可调的整形脉冲,改变了过去那种只把普克尔盒当作简单的削波元件、而无整形能力的状况。并提出了采用双块晶体、补偿结构KTP普克尔盒的设想。
本文导出了从吸收媒质上反射的s和p两种偏振的Goos-Hnchen位移的一般表达式。若令消光系数等于零,它们就简化成McGuilk和Carniglia给出的仅用于非吸收媒质的公式。吸收媒质的位移,在任何不为零的入射角度时都有。在镓的表面上,位移有几个波长。
研究了自保护药芯焊丝激光-电弧复合堆焊的熔滴过渡行为。结果表明，激光的加入明显减小了电弧斑点的漂移概率，拉伸了电弧空间，改变了熔滴受力状态及其过渡行为。激光前置比后置时更有利于熔滴过渡和电弧稳定性的提高。自保护药芯焊丝激光-电弧复合堆焊的最佳工艺参数为：激光前置，激光功率2 kW，光丝间距 4 mm，光斑直径为2 mm，光丝夹角30°。当光丝间距小且激光功率为4 kW时，熔滴过渡形式由排斥过渡变为爆炸过渡。
We propose a novel photonic technique for microwave frequency measurement based on transversal microwave filters with high resolution. Two parallel microwave filters with sine and cosine frequency responses are obtained by cross gain modulation in a singl

Self-compression of loosely focused pulses in gases with power close to self-focusing critical value
It is observed that the pulse duration of loosely focused pulses is self-compressed during the nonlinear propagation in argon when the input pulse peak power is close to the threshold power for self-focusing, and the results are confirmed by the numerical
