准相位匹配PPMgLN腔内倍频绿激光器研究进展

Research Progress of Green Lasers Based on Quasi-Phase-Matched Intracavity Frequency Doubling in PPMgLN

结构紧凑、效率高、性能稳定的绿激光器在光存储、激光打印、舞台表演、医疗、水下通信等领域,尤其是激光显示领域具有广泛应用。由于缺乏相应输出波长的高效半导体绿激光器,基于倍频技术的全固态激光器仍然是产生绿色激光最有效的方法。近年来,随着周期性极化技术的成熟,准相位匹配PPMgLN倍频绿激光器发展迅猛。本文综述了PPMgLN腔内倍频绿激光器的结构、性能优势及发展现状。

Green lasers having a compact structure,high efficiency,and stable performance are widely used in optical storage,laser printing,stage performance,medical treatment,and underwater communication,particularly in laser displays.All-solid-state lasers based on frequency doubling technology are currently the most effective means of generating green lasers because of the lack of efficient semiconductor lasers having the corresponding output spectrum.With the developed technology of a periodically poled crystal,green lasers based on quasi-phase-matched intracavity frequency doubling in PPMgLN have been rapidly developed in recent years.Hence,this study reviews the multiple structures,performance advantages,and development status of green lasers based on PPMgLN.
