In the process of experiment investigation on photonic crystal fiber fabricated by ourselves,by increasing the central wavelength of pump pulseλ_0 gradually,the frequency spectrum of pump pulse is widening gradually withλ_0 approaching toλ_D,at the same time,and the intensity of anti-Stokes wave is increasing gradually with the transform-efficiency being enhanced.
在对自行设计的光纤进行实验研究的过程中,通过逐渐增加泵浦脉冲的中心波长λ_0发现随着λ_0逐渐接近零色散波长λ_D,在一系列非线性效应的作用下泵谱脉冲的频谱逐渐展宽,同时其转化效率也逐渐增加,在短波段的反斯托克斯波的强度也逐渐增加。
As the solution of the two equations for determining the existing fifth order Stokes wave derived from Skjelbreia was rather complex and tedious,this paper simplifies the two equations into one equation for determining d/L,i.
由于Skjelbreia导出的确定五阶斯托克斯波的二个方程不易求解,本文将其简化为确定d/L的一个方程:f(H,T,d,d/L)=0。
