The research status of two active laser crystal fields, Yb doped crystals and Raman crystals, are reviewed. Yb-doped crystals can produce high power laser output, and they are very important research fields. And fs (femtosecon) laser outputs from Yb-doped crystals can be obtained pumped by laser diode. Many wavelength laser can be produced by using Raman crystal, so Raman crystal may have many potential applications. The advantages, possible applications and new developments are also expatiated in this paper.
