Abstract: A single-longitudinal-mode dual-wavelength fiber laser can be used to generate millimeter waves is presented. Polarization-maintaining fiber Bragg grating (PM-FBG) is used as wavelength selected component in this laser. Two wavelength of PM-FBG is orthogonal polarization states, enhance the polarization hole burning effect and effectively reduce the different wavelength competition and achieve stable dual-wavelength output. The Vernier effect of the compound cavity, effectively suppress multi-modes oscillations and realize single-longitudinal-mode operation. The separation of two wavelength is 0.318nm (39.8 GHz) and SMSR is more than 50dB.
