Research Progress of All-Solid-State Yellow Lasers

Due to the wide applications of yellow laser in the fields of biomedicine, detection and identification of space object,laser display and chemistry, extensive research on all-solid-state yellow lasers has been carried out recently.The development history and status quo of all-solid-state yellow lasers were briefly covered. Different ways to generate yellow laser were discussed, especially two nonlinear-optical methods of sum-frequency mixing and stimulated Raman scattering (SRS). In the discussion of sum-frequency mixing, the intracavity and extracavity sum-frequency generations were compared. Three different technical approaches of all-solid-state Raman yellow lasers were analysed.The research of infrared sources directly frequency-doubled to obtain yellow laser was simply introduced.Finally the development trend of all-solid-state yellow lasers was pointed out.
