| 摘 要： | 本文考察了光纤中外加可调谐信号光条件下的受激拉曼散射现象,提出一种新的宽带光纤拉曼相干光源的设想。这种光源是利用波长可调的弱信号光来调制固定波长的强泵浦光在光纤中产生的高阶受激拉曼散射,使得高阶受激拉曼散射Stokes峰值波长随弱信号光的波长改变而改变。从而获得一个输出均匀而频带又比信号光宽得多的高强度相干光。

| Abstract: | We have investigated the stimulated Raman scattering (SRS) in fibers with the participation of an external tuning signal light, and proposed a new idea for designing a wide-band fiber-optic Raman coherent source, in which the high-order stimulated Raman scattering generated by pump light with a constant wave length is modulated with a tunable weak signal light and the peak wavelengths of Stokes components of SRS change with the change of wavelength of the weak signal light. Thus the high-intensity and well-dis- tributed coherent output, of which the frequency band is much wider than that of the signal light, is obtained. |
