摘要
与传统的边发射半导体激光器相比,垂直腔面发射激光器(VCSEL)具有线宽窄、光束质量好、可靠性高和制造成本低等优点。随着808nm VCSEL阵列的输出功率和转换效率的提高,VCSEL阵列成为了固态激光器抽运源的新选择。介绍了VCSEL的性能优势、应用场合及发展现状,综述了VCSEL阵列抽运的固态激光器的研究进展,讨论了其技术缺陷及发展前景。
When compared with the traditional edge-emitting semiconductor lasers,the vertical-cavity surface emitting lasers(VCSELs)offer several advantageous properties,including a narrow line width,superior beam quality,high reliability,and low manufacturing cost.Recently,with an increase in the output power and power conversion efficiency of the 808 nm VCSEL arrays,they have become an attractive alternative for the pumping sources of solid-state lasers.In this study,we introduce the performance advantages,applications,and status of the VCSELs.As for the VCSEL-array-pumped solid-state lasers,the research progress is reviewed,and the development prospect as well as their technical shortcomings are discussed.
