摘　　要：The Raman gain coefficients in polarization maintaining photonic crystal fibers （PM-PCFs） are analyzedin in order to design fibers for linearly polarized Raman fiber laser with enhanced performances. The results show that a well designed germanium-doped PM-PCF can attain the value of Raman gain coefficient over 50 W^-1·km^-1, going with very high birefringence and single mode operation at 1.55-μm signal wavelengthand 1.45-μm pump wavelength.The Raman gain coefficients in polarization maintaining photonic crystal fibers （PM-PCFs） are analyzedin in order to design fibers for linearly polarized Raman fiber laser with enhanced performances.
