High performance, short coherence length light sources with broad bandwidths and high output powers are critical for high-speed, ultrahigh resolution OCT imaging. We demonstrate a new, high performance light source for ultrahigh resolution OCT. Bandwidths of 140 nm at 1300 nm center wavelength with high output powers of 330 mW are generated by an all-fiber Raman light source based on a continuous-wave Yb-fiber laser-pumped microstructure fiber. The light source is compact, robust, turnkey and requires no optical alignment. In vivo, ultrahigh resolution, high-speed, time domain OCT imaging with <5 microm axial resolution is demonstrated.
具有宽带宽和高输出功率的高性能、短相干长度光源对于高速、超高分辨率光学相干断层扫描(OCT)成像至关重要。我们展示了一种用于超高分辨率OCT的新型高性能光源。基于连续波镱光纤激光泵浦的微结构光纤的全光纤拉曼光源,在中心波长1300nm处产生了带宽为140nm且输出功率高达330mW的光。该光源紧凑、坚固、交钥匙即用且无需光学对准。在体内,展示了轴向分辨率小于5微米的超高分辨率、高速时域OCT成像。
