Nanya University Laser Application Innovation Research Institute published the research results of ultra -high -power fiber laser lasers

Recently, Sun Jiapo (First Author), Professor Liu Lie, and Teacher Han Lianghua (co -communication author) at the Nanya University Laser Application Institute of Laser Application Innovation Research Institute (first author) published a 100 kW super in the American Optical Society (OSA) journal Optics Continuum (Formerly Osa Continuum) The latest article of high -power fiber laser "100 KW Ultra High Power Fiber Laser", which first reported the joint development of China's first high -performance 100 KW industrial optical fiber with the first high -performance 100 KW industrial optical fiber in China and Ruike Laser units. Laser.

In this study, the laser is based on the independently developed light -derived large -model field gain fiber and the 976nm lock wavelel long high power high -brightness high -brightness pump source, which uses a secondary 7 × 1 optical fiber power beam technology to achieve 101.65 kW 101.65 kW The maximum laser power output, the center wavelength is 1080 ± 5 nm, the spectrum bandwidth is 5-8 nm, the output fiber core diameter is 400 μm, the beam quality BPP is 19.28 mm*mRAD, the laser power is unstable ± ± ± 1.1%. Its laser -free package layer stripping technology, distorting cone technology, beveled multi -tube core condensation technology, and circular inner packaging modification design have reached the international advanced level.

The joint development of this laser is a model of school -enterprise cooperation and the results of the introduction of school talents. In the future, the retirement and demolition of nuclear facilities in nuclear facility pipelines and radiation environments, the surface of nuclear pollution components can be used High -end applications such as waste liquid glass curing.

In addition, the postgraduate of the Laser Application Institute Yu Shiwei is the first author, and Professor Liu Lie's article "Ultra-High Power Laser for Vitridation of Borosility Glass" has been hired by the international journal AIP Advances. It is expected The monthly publication, follow -up related research results will be further reported.

论文摘要: Based on the self-developed non-photodarkening large mode field gain fiber and the 976 nm wavelength-locked high-power and high-brightness pump source, and using the secondary fiber power combining technology, a high-performance 100kW fiber laser in China was built, realizing high-order mode and non-linear effect suppression. The maximum output power of the laser can reach 101.65 kW, the center wavelength is 1080 ± 5 nm, the spectral bandwidth is (3dB) 5-8 nm, the output fiber core diameter is 400µm, the beam quality BPP is 19.28 mm*mrad, and the laser power instability is ±1.1%. Its laser non-destructive cladding stripping technology, distortion-free taper technology, inclined multi-die beam combining technology And Circular Inner Clading Modification Design Have All Reached the International Advanced Level.
