     An atomic Faraday anomalous dispersion optical filter(FADOF),which characterized with its ultra narrow peaks of wavelength transmissions,is employed to improve the frequency stability of a semiconductor laser. The FADOF is put into the external cavity of the semiconductor laser as a frequency selector to restrain the lasing wavelength to the transmission wavelength of the FADOF,and in this way,the laser frequency locked to the atomic transmission is realized effectively through the optical feedback.

An electro-optically fast-tuning ruby laser, which consists of a calcite-KDP crystal as the fast-tuning component and a Fabry-Perot resonant frequency selector as the fine wavelength controller, has been developed for a differential absorption lidar(DIAL)system for water vapor sounding in the atmosphere. The laser has stepwise tuning characteristics and emits two pulses in a single shot, with the first pulse tuned at the center of an absorption line of the water vapor and the second one in the nearby valley....

An electro-optically fast-tuning ruby laser, which consists of a calcite-KDP crystal as the fast-tuning component and a Fabry-Perot resonant frequency selector as the fine wavelength controller, has been developed for a differential absorption lidar(DIAL)system for water vapor sounding in the atmosphere. The laser has stepwise tuning characteristics and emits two pulses in a single shot, with the first pulse tuned at the center of an absorption line of the water vapor and the second one in the nearby valley. Operation theory and tuning characteristics of the laser are discussed in detail.

研制了一种电光快速调谐红宝石激光器。方解石-KDP晶体组成快速调谐部件,F-P共振选频元件用于进一步精确控制波长,并形成阶跃式的调谐曲线,在一次点火中即能输出波长不同的两个脉冲。文中对激光器工作原理和调谐特性作了详细分析。

After studying alternating projection neural networks proposed by MarksⅡ etc.. This paper extends it from the field of real unmbers to the field of complex numbers, gives its convergent condition and the convergence proof of APNN. Then several useful conclusions are obtained by studying alternation projection neural networks operating in the field of complex numbers (the extended network is called complex alternating projection neural networks), and the strict mathematical proofs are provided for these conclusions. Finally, a simulational experiment is designed to validate the theoretical analysis, the experimental results demonstrate a reasonably good agreement between theory and experiment. In practice complex alternating projection neural networks can be widely applied to signal processing, such as band-limited signal extrapolation, frequency selector and trap filter.
