可见光激光二极管的开发现状与市场——780nm GaAlAs可见光LD

The Development Status and Market of Visible Laser Diodes——780nm Wavelength GaAlAs Laser Diodes

文章主要介绍国外可见光激光二极管(LD)的开发现状,其中包括所用材料、波长、器件结构、工艺、主要性能参数、产销量、价格以及应用领域,并对其发展趋势做了肤浅的展望。鉴于内容广泛,资料丰富,故采取分篇介绍。第一部分介绍780nm 波长的可见光 LD;第二部分则着重于 GaAlAs 大功率可见光 LD;第三部分介绍600nm 波段四元材料可见光 LD;第四部分介绍整个半导体可见光 LD 的市场情况。本文介绍其中第一部分。

The development status and market of visible laser diodes in foreign countries are described in this paper,which includes devjec materials. waretength,structures,main performance parameters,production and sale amounts. price as well as applications,and the prospeot for the devclopmental tendency of the devices is simply predicted.Because of rich information content and limited space,this paper will be published section by section.GaAIAs/GaAs visible laser diodes operating at 780nm wavelength will be given in the first section;high powet GaAIAs/GaAs visible laser dicdes,in the second;visible laser diodes operating at 600nm wavelength,in the third;and the market status for visible Iaser diodes,in the last section.The first section goes as follows.
