| Abstract: | Laser frequency conversion is a key technology in laser application. Solid-state Raman crystals suitable for stimulated Raman scattering are used to frequency shift of high-peak laser pluses with high efficiency and high optical beam quality. This technology is an important trend for laser frequency conversion especially with the development of Q-switching and mode-locking technology. Raman frequency shift, line width, integral and peak Raman scattering cross section and Raman gain coefficient are proposed as the parameters to evaluate Raman materials. According to the structure of materials, Raman crystals can be divided into scheelite type, wolframite type, bitungstate and zirconite type. The properties of those crystals and development prospect of Raman crystals for laser shifting are discussed. |
