摘要
激光因在时域、频域、空间和相位等多个维度的物理特性具有重要科学研究和应用价值。尤其是Tm^(3+)、Ho^(3+)掺杂的2μm固体激光具有宽带宽、高增益、模式灵活选择以及波长可被大气分子吸收等特点,在光电对抗、医疗诊断、新波段通信和阿秒光源等领域有着重要的应用前景。本文针对2μm波段超快固体激光研究现状,梳理和分析了该波段固体超快激光多维度调控方面的研究历程、理论基础、技术进展和应用现状,并进一步展望了人工智能驱动下的中红外激光多维度调控的发展前景。本文将为中红外新体制超快激光的波长扩展和空间维度扩展等新兴研究提供参照。
Lasers have important scientific research and application values due to their physical properties in multiple dimensions such as time domain,frequency domain,space,and phase.In particular,Tm^(3+)and Ho^(3+)doped 2μm solid-state lasers possess new characteristics such as wide bandwidth,high gain,flexible mode selection,and atmospheric molecular absorption,and have important application prospects in fields such as electro-optical countermeasures,medical diagnosis,new-band communication,and attosecond light sources.This paper focuses on the research status of 2μm band ultrafast solid-state lasers,reviews and analyzes the research history,theoretical basis,technological progress,and application status of multi-dimensional regulation of solid-state ultrafast lasers in this band,and further looks forward to the development prospects of mid-infrared laser multi-dimensional regulation driven by artificial intelligence.This paper will provide a reference for emerging research such as wavelength expansion and spatial dimension expansion of new mid-infrared ultrafast laser systems.
