Research progress of crystalline Raman yellow lasers

Yellow light sources, emitting between 570 nm and 600 nm, are interesting for their potential in several application fields and are irreplaceable to a certain extent in certain characteristic domains. Therefore, it has been a research hotspot in the field of laser technology. A crystalline Raman yellow laser is an important approach to achieving yellow light sources. This paper focuses on an important branch of all-solid-state yellow laser, i.e. crystalline Raman yellow laser, and discusses its research progress in the past twenty years by summarizing a few classic works. The paper clarifies the implementation schemes of crystalline Raman yellow lasers for different application requirements, providing a reference for future research in this field.
