Abstract

All-solid-state 2 μm ultrafast laser sources exhibit significant potential in diverse application fields. Their wavelength falls within the atmospheric window, effectively covering the absorption spectral lines of numerous molecules. The picosecond all-solid-state laser sources with a centre wavelength of 2 μm serves as a prime example, gaining prominence in the mid-infrared ultrafast laser domain recently. This paper first outlines several representative 2 μm solid-state ultrafast lasers. It then elaborates on crucial technologies for generating 2 μm ps lasers, focusing on mode-locking techniques. Additionally, it reviews recent progress in picosecond Tm³⁺/Ho³⁺ ions-doped all-solid-state laser sources operating in the 2 μm wavelength range. What's more, the discussion highlights key applications of all-solid-state picosecond laser sources that utilize Tm³⁺ and Ho³⁺. In conclusion, the paper traces the evolution of picosecond all-solid-state laser sources with a central wavelength of 2 μm and offers perspectives on future advancements.
