We report a diode-pumped Q-switched Nd:YAG-KGW Raman laser operating in two-color modulation. The output wavelength can be switched between 1159 nm and 1177 nm using an E-O switch, and the Raman output modulated in spectra-time domains was achieved. Raman pulse energy up to 114 mJ at 1177 nm and 98 mJ at 1159 nm were obtained respectively, corresponding to an overall Diode-Stokes conversion efficiency of 15.3% at 1177 nm and 13.2% at 1159 nm.
