Research Progress on Multi-dimensional Manipulation of 2 μm Solid-state Lasers

Abstract 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 2 m 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 2 m 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.
