设计并拉制了零色散波长在800 nm附近的折射率引导型光子晶体光纤, 仿真结果表明光子晶体光纤的基模零色散波长在825 nm处, 并能在基模下产生四波混频现象(FWM)。使用中心波长为810 nm的200-fs Ti宝石激光器抽运, 在短波段610 nm处出现了显著的反斯托克斯效应, 输出信号光为高斯形, 这表明在光子晶体光纤的基模下产生了反斯托克斯光。产生的反斯托克斯信号的能量远远高于剩余抽运激光的能量, 输出的反斯托克斯光和抽运光的频谱之比超过了1.2, 其转化效率超过了50％, 很好的实现了波长转换。

A photonic crystal fiber(PCF) with zero dispersion wavelength around 800 nm is designed and fabricated. The simulated results show that the zero dispersion wavelength of fundamental mode of the PCF is at 825 nm and FMW is possible in fundamental mode. Anti-Stokes line around 610 nm can be generated efficiently with 810nm 200 fs Ti∶Sapphire laser used as pump. The output signal has a Gauss like field, which indicats that anti-Stokes signal is in the fundamental mode of PCF. The output energy of anti-Stokes signal is much more than the energy of residual pump laser. The maximum ratio of the anti-Stokes signal energy to the pump component in the output spectrum is estimated as 1.2 and the conversion efficiency is above 50%, wavelength conversion is achieved commendably.
