| 摘 要： | 利用自制的高非线性光子晶体光纤进行了飞秒激光脉冲传输实验,研究了在不同功率、不同输入波长下高非线性光子晶体光纤的频率转换现象。当输入激光脉冲的中心波长位于光子晶体光纤反常色散区800nm处时,输出光谱向短波方向展宽,其产生的反斯托克斯波强度随输入功率增强逐渐增强;当输入激光脉冲的中心波长在反常色散区不同波长下时,光纤的频率转换效率不同,越接近零色散波长,转换效率越大,当输入脉冲中心波长为760nm时,产生的反斯托克斯波的中心波长为465nm,其强度是抽运波剩余强度的8.1倍,转换效率高达90%。

| Abstract: | Femtosecond pulses transmit is demonstrated in a highly nonlinear PCF. Erequency conversion in abnormal dispersion region of a highly nonlinear PCF at the different power and wavelength is studied by Femtosecond Laser Pulses. An 800 nm central wavelength of input pulses locates in the abnormal dispersion region of the PCF. The output spectrum spreads to short wavelength, and the anti-stokes emission in output spectrum holds on dominant status gradually when the average power of initial input pulses increase... |
