|
Abstract:
窄线宽532 nm在高反金属材料加工、荧光检测、紫外波段和中红外波段激光的产生等领域均有广泛的应用。近红外波段1064 nm光纤激光腔外倍频产生的532 nm具有噪声低、效率高，光束质量好和功率稳定性好等优点。本文从常见的腔外倍频结构和晶体出发，对四种常见倍频晶体的有效非线性系数、激光损伤阈值进行分析对比；重点总结了窄线宽光纤激光单通双折射晶体、周期性极化晶体产生绿光；角度匹配、温度匹配下外腔谐振倍频产生532 nm激光的研究进展。讨论了腔外倍频中两种结构的特性和应用场景。
The narrow-linewidth of 532 nm is widely utilized in various domains, including high-reflectance metal material processing, fluorescence detection, and the generation of laser in the ultraviolet and mid-infrared spectral ranges. The 532 nm generated through extracavity frequency doubling of a 1064 nm near-infrared fiber laser boasts advantages such as low noise, high efficiency, good beam quality, and stable power. This paper initiates its exploration from common extracavity frequency-doubling structures and crystals, conducting a comparative analysis of the effective nonlinear coefficients and laser damage thresholds of four commonly used frequency-doubling crystals. It places particular emphasis on summarizing the production of green light using narrow-linewidth fiber lasers through single-pass birefringent crystals and periodically poled crystals. The research progress in external cavity resonant frequency doubling for 532 nm laser generation under angle matching and temperature matching is elucidated. The characteristics and application scenarios of the two extracavity frequency-doubling structures are discussed.
