Supercontinuum Generation in Photonic Crystal Fiber by Femtosecond Pulses Laser
光子晶体光纤 超连续光谱 飞秒脉冲激光 掺钛蓝宝石激光 photonic crystal fiber supercontinuum spectrum femtosecond pulsed laser Ti:sapphire laser
摘要
将单脉冲能量约为2.5 nJ、脉宽为25 fs、对应峰值功率为0.1 MW的的800 nm钛宝石激光耦合到长为 10 mm,芯径为1.8 μm的光子晶体光纤中,产生了耦合效率约为17%、谱宽覆盖可见光及近红外波段的超连续光谱。
Abstract
Supercontinuum light with a spectrum covering visible range was generated in a photonic crystal fiber launched by the 25 fs laser pulse train from a Ti: sapphire laser oscillator at 800 nm wavelength. The fiber has a core diameter of ~1.8 μm and a length of 10 mm. By setting the laser energy at 2.5 nJ, it corresponds a peak power of about 0.1 MW, respectively, coupling efficiency of 17% was demonstrated.
