The passively quenched operation of avalanche photodiode (APD) has been used to characterizing InGaAs/InP APD including punch through voltage, avalanche voltage and break down voltage that are all important in the design of APD for single photon detection
研究了不同有机溶剂对光声信号的增强作用。从理论和实验上探讨了溶剂特性与光声信号强度的关系,得到各种溶剂的光声信号增强系数。
激光的出色特点,已为人们所熟知,关于它的应用也有许多叙述。激光在计量方面的应用是极有前途的一种应用,由于接二连三的研究正在进行,所以这里尽可能避免与迄今为止的那些讲述相重复,只限于介绍激光在精密测量中的应用及其必要的基础知识。同时,文中略去了有关一些建议和设想的介绍,而对基础实验完成了的或产品化了的东西则作尽可能详尽的叙述。至于激光器的构造和特性,请参阅文献[1]等综述性文章。

用解析法研究了非局域非线性介质构成的平板波导中正交偏振、中心重合的双高斯光束的传输规律,得到了两光束各参量的演化方程和两个临界功率,其大小与耦合系数m和非局域程度有关。在无双折射的情形下,当两光束初始束宽相等时,临界功率也相等。当光束初始功率等于临界功率时,得到了两个正交偏振的高斯型线偏振空间孤子,其与介质的非局域程度无关。对于强非局域情形,在无双折射条件下,得到了光束各参量的演化解析表达式。当总功率等于临界功率,而两光束功率不相等时,得到了两个正交偏振的高斯型呼吸子,功率大的光束束宽作周期压缩振荡,功率
