A diode-pumped Q-switched Nd:YAG-KGW Raman laser operating in dual-wavelength modulation is reported. The novel design of segmented circular laser diode (LD) arrays side-pumped structure with conductive and air cooling has great potential to be used in compact and miniature laser systems. The output wavelength of the 1 159 nm and 1 177 nm modulated in spectra-time domains is achieved by an E-O switch, and first-stokes pulse output modulated at spectra-time two-dimensional domains. Pulse energy up to 114 mJ at 1 177 nm and 98 mJ at 1 159 nm are obtained respectively, corresponding to diode-stokes efficiency of 15.3% at 1 177 nm and 13.2% at 1 159 nm.
