摘要
受波导结构和芯片封装等因素的限制,半导体激光器快慢轴方向上的光束质量差距较大。半导体激光器主要用作抽运源,即亮度转换器,很难作为高亮度光源被直接应用。介绍了提高半导体激光器输出光功率密度和输出光束质量的非相干合束技术--波分复用合束技术,并总结了其国内外发展现状及若干重要动向。该研究为半导体激光器波分复用合束技术的发展提供了参考。
Abstract
Due to the limitations of waveguide structure, chip packaging and other factors, the beam quality of diode lasers in fast axis is different from that in slow axis. Diode lasers are usually used as pumping source, i.e., luminance converter, and cannot directly act as a high-brightness laser source. We introduce an incoherent beam combining technology, called wavelength division multiplexing (WDM) beam combining technology, and it can improve the output optical power density and output beam quality of diode lasers. We summarize its development status and some important trends at home and abroad. The study provides a reference for the development of diode laser WDM beam combining technology.
