摘要

本文介绍了一种基于掺铒光纤，利用自孤子频移技术和PPLN晶体作为二次谐波产生模块的紧凑、可调谐飞秒激光器。实现了无与伦比的频率转换效率高达55%的800 - 850纳米波长范围内，这款紧凑型激光器发射低于100 fs脉冲。激光在第一和第三生物窗口内同时工作，分别提供10.4 nJ和5.1 nJ的脉冲能量。这种性能，以前在类似的系统中未达到，同时保持二次谐波发电功率稳定性低于2% RMS。本发明用于多光子显微镜膀胱癌检测的紧凑型激光器，将显著提高系统的紧凑性、精度和肿瘤检测效率。

Compact femtosecond fiber laser tunable from 800 to 850 nm with pulse energy exceeding 5 nJ.

This paper introduces a compact, tunable femtosecond laser based on an Erbium-doped fiber, utilizing the Self-Soliton Frequency Shifted technique and PPLN crystal as a Second Harmonic Generation module. Achieving an unparalleled frequency conversion efficiency up to 55% for the 800 - 850 nm wavelength range, this compact laser emits sub-100 fs pulses. The laser operates simultaneously within the first and third biological windows, delivering pulse energies of 10.4 nJ and 5.1 nJ, respectively. This performance, previously unattained in similar systems, is achieved while maintaining Second Harmonic Generation power stability below 2% RMS. The presented compact laser, developed for bladder cancer detection through multiphoton microscopy, will significantly improve the system's compactness, precision, and cancer detection efficiency.
