Abstract：Lasers have importantscientific research and applicationvalues dueto their physical properties in multiple dimensions such as time domain，frequency domain，space，and phase.In particular，Tm and Ho3+ doped 2μm solid-state lasers possess new characteristics such as wide bandwidth，high gain，flexible mode selection，and atmospheric molecularabsorption，and have important application prospects in fields such as electro-optical countermeasures，medical diagnosis，new-band communication，and atosecond light sources.This paperfocuses on the research status of 2μm band ultrafast solid-state lasers，reviews and analyzes theresearch history，theoretical basis， technological progress，andapplication statusof multi-dimensionalregulationof solid-stateultrafastlasers in this band，and furtherlooks forward tothedevelopmentprospectsofmid-infrared laser multi-dimensionalregulationdriven byartificial inteligence.This paper willprovide areference for emerging research suchas wavelength expansion and spatial dimension expansion of new mid-infrared ultrafast laser systems.
