| Abstract: | The absorption spectra characters of the (Cr,Yb):YAG,Cr:YAG and Yb:YAG crystals are reported. In the absorption spectra of the (Cr,Yb): YAG crystal,there are two absorption bands at 937 nm and 968 nm respectively,which are suitable for InGaAs diode laser pumping；and there is an absorption band of Cr4+ near 1030 nm,which is suitable for passive Q switch laser output at 1.03 μm. This Cr-Yb-codoped crystal may be a potential material for compact,diode laser pumped passive Q-switched solid-state laser with efficient,high-stable. |
