We report smooth and broad continuum generation using a compact femtosecond Ti:Sapphire laser as a pump source and a tapered photonic crystal fibre as a nonlinear element. Spectral output is optimized for use in optical coherence tomography, providing a maximum longitudinal resolution of 1.5 microm in free space at 809 nm centre wavelength without use of additional spectral filtering.
我们报道了利用一台紧凑型飞秒钛宝石激光器作为泵浦源以及一根锥形光子晶体光纤作为非线性元件实现了平滑且宽谱的连续谱产生。光谱输出针对光学相干断层扫描应用进行了优化,在中心波长为809 nm的自由空间中提供了1.5微米的最大纵向分辨率,且无需使用额外的光谱滤波。
