Abstract

A type of Tm-doped silica fiber laser with narrow-linewidth and output wavelength near 1750 nm was firstly presented, by using a 1550 nm Er-doped fiber laser pump source and a volume Bragg grating (VBG). By means of a 15 cm Tm-doped fiber, a 400 mW continuous wave (cw) at ~1750 nm with FWHW of ~54 pm was generated, corresponding to an average slope efficiency up to 23.5% with respect to absorbed pump power. The influence of gain fiber length on the spectrum wavelength has been investigated in detail. All experimental results demonstrate that this fiber laser will be an effective and promising pump source for mid-IR laser output.

摘要

首次提出了一种具有窄线宽且输出波长接近1750 nm的掺Tm石英光纤激光器，该激光器采用1550 nm掺Er光纤激光泵浦源和体布拉格光栅（VBG）。借助15 cm长的掺Tm光纤，在~1750 nm处产生了400 mW的连续波（cw），其半高宽（FWHW）约为54 pm，相对于吸收的泵浦功率，平均斜率效率高达23.5%。详细研究了增益光纤长度对光谱波长的影响。所有实验结果表明，这种光纤激光器将成为用于中红外激光输出的一种有效且有前景的泵浦源。
