Problems solved by technology

In this solution, in order to provide sufficient amplification gain, it is generally necessary to use hundreds of meters of optical fiber, and high-order Raman will seriously affect the development of the system to high power
[0007] In summary, although researchers have proposed the above-mentioned various narrow-linewidth long-wavelength fiber laser generation methods and power boosting methods, the technical solutions for realizing high-power narrow-linewidth long-wavelength fiber laser are still very scarce.

Abstract

A high-power narrow-line wide-long-wave fiber laser generating system comprises an optical fiber laser system array, a wavelength division multiplexing system and a hybrid gain optical fiber amplifier; wherein the hybrid gain optical fiber amplifier comprises a fundamental frequency optical pumping source, a full optical fiber signal-pumping beam combiner and a large-mode field ytterbium-doped optical fiber. The influence of the raman pumping light time-frequency characteristic on the spectral broadening characteristic of the raman amplification laser and the influence of incident laser time frequency characteristic on the spectral broadening characteristic of the raman amplification laser spectrum when the ytterbium ions gain is directly amplified are utilized to effectively suppress thespectral broadening in the amplification of the hybrid gain long-wave optical fiber through incident laser implementation mode, raman pump light generation form and the like. A high-performance optical fiber light source design scheme with reliable performance and compact structure is provided for the fields of nonlinear frequency conversion, biomedicine, remote sensing detection, high-resolutionspectral imaging and spectral synthesis. Further, development of the narrow-line wide-long-wave fiber laser radiation field is promoted.

Description

technical field [0001] The invention belongs to the technical field of strong laser and nonlinear fiber optics, in particular to a high-power narrow-linewidth long-wave fiber laser generation system. Background technique [0002] The high-power narrow-linewidth long-wavelength fiber laser with a wavelength coverage of 1000-1300nm has strong application requirements and development potential in the fields of nonlinear frequency conversion, biomedicine, remote sensing detection, high-resolution spectral imaging, and spectral synthesis. [0003] At present, the main ways to generate high-power narrow-linewidth long-wavelength fiber laser output include the following three types: [0004] (1) Based on the emission characteristics of ytterbium ions in the long-wavelength band, direct use of narrow-linewidth laser injection and Ytterbium-doped fiber laser amplifiers to achieve narrow-linewidth long-wavelength fiber laser amplification output. In this scheme, due to the small emis...
