900nm nanosecond fiber laser

Recently, the Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, has made a breakthrough in the research of all-optical fiber 900 nm band nanosecond fiber lasers. Based on the full link self-developed domestic neodymium doped silica fiber, it has achieved 100 μ focal laser output for the first time.

The laser uses a continuous narrow spectrum 922nm fiber oscillator as the seed source. After acousto-optic modulation, it is amplified in three stages to achieve an average power of 12W, a repetition rate of 100kHz, a pulse width of 37ns, and a single pulse energy of 120 μ J. The research results are expected to further promote the development and application of 900nm nanosecond fiber lasers
