In this paper, the fabrication and testing results of a two-dimensional pin-cushion position sensitive detector (PSD) are presented. The obtained pin-cushion PSD with an 8 * 8 mm2 effective area presents a maximum spectral response of 0.5 mA/mW at 850-nm wavelength, a 12-nA dark current at 5-V reverse voltage, a reverse breakdown voltage of 50 V, a nonlinearity of 2.175%, and a spatial resolution of 10 um. The spatial resolution is relatively low and the slight pin-cushion concave distortion is generated due to the incompletely satisfied relationship between sheet resistivity of the anode and the resistance per unit length.

Space-division multiplexing (SDM) has attracted significant attention in recent years because larger transmission capacity is enabled by more degrees of freedom (DOFs) in few-mode fibers (FMFs) compared with single-mode fibers (SMFs). To transmit independ
美帝阿多耳夫·迈勒公司供应一种优质矾土陶瓷光学平面垫圈,以增进激光共振反射器的反射率。将垫圈之一放到两个青玉共振反射器(标准具)中,可得60%~66%的反 射率。使用三台适当间隔的标准具和两个垫圈,反射率约为80%。据报导,具有三个垫圈的四台标准具的列阵,产生的反射率约为96%。

本文介绍一种利用倍压和全波整流复合的新型电路所研制的CO2激光器电源。使用该电源不仅可使CO2激光器的输出激光功率从0到满功率范围连续可调,输出激光平均功率的起伏小于±5%,而且可使CO2激光器以脉冲和连续两种状态工作。
We report the experimental study on mode instabilities (MI) in large mode area step-index fibers by testing a 30/400 mm step-index fiber in a single-pass co-pumped all-fiberized amplifier, delivering up to ~550 W of extracted output power without MI. The
The evolution of the spin density vectors (SDVs) is studied in a strongly focused composite field. It is found that the SDVs can be spiral along the propagation axis, and they are perpendicular to the
