光纤激光器光纤放大器中红外激光超连续谱激光源 fiber laser fiber amplifier mid-infrared laser supercontinuum laser source

摘要

报道了一个高功率全光纤结构的中红外超连续谱激光源，该光源由1.55 μm纳秒脉冲掺铒光纤激光器、包层抽运掺铥光纤放大器以及单模ZBLAN光纤组成。首先利用单模光纤将1.55 μm纳秒脉冲激光频移至2.0 μm波段，然后利用掺铥光纤放大器对其进行功率放大，最后利用ZBLAN光纤使掺铥光纤放大器输出的光谱进一步向中红外长波长方向扩展。当掺铥光纤放大器输出功率为3.95 W时，ZBLAN光纤产生了2.2 W的中红外超连续谱激光输出，相应的光谱范围为1.9~3.75 μm，10 dB光谱带宽大于1600 nm。此外，通过增加掺铥光纤放大器的平均输出功率，中红外超连续谱的输出功率得到了进一步提高，当耦合进单模ZBLAN光纤的平均功率为21 W时，中红外超连续谱的平均输出功率达到了16.2 W，相应的光谱范围为1.9~3.5 μm。

Abstract

A high-power all-fiber mid-infrared supercontinuum laser source that consists of a 1.55 μm nanosecond-pulsed erbium-doped fiber laser, a cladding-pumped thulium-doped fiber amplifier and a segment of single-mode ZBLAN fiber is reported. Firstly, the pulse breaks up through modulation instability and the laser shifts to a longer wavelength through Raman processes in the single-mode fiber. Secondly, the nanosecond pulses are amplified through a thulium-doped fiber amplifier. Finally, the output spectrum from the thulium-doped fiber amplifier is extended to the mid-infrared wavelength by using a segment of single-mode ZBLAN fiber. The output power from the ZBLAN fiber is 2.2 W with the launched pump power of 3.95 W at 2.0 μm wavelength region, the emission spans the wavelength range from 1.9 μm to 3.75 μm with a 10 dB bandwidth of greater than 1600 nm. In addition, a higher output power mid-infrared supercontinuum laser source is achieved by increasing the average output power of the thulium-doped fiber amplifier. The ZBLAN fiber produces an average output power of 16.2 W with the coupling pump power of 21 W at 2.0 μm wavelength region, the emission spans the wavelength range from 1.9 μm to 3.5 μm.
