    Abstract

    Conclusions

    An optical structure with a single fiber dual-wavelength output and self-inspection function is designed using spatial combining, wavelength beaming, and beam shaping techniques. We obtain a 976 nm ignition laser with an output power greater than 10 W and a 1310 nm detection laser with an output power greater than 1 mW. The structure can simultaneously realize the power and optical path self-inspection of 976 nm ignition and 1310 nm detection laser. The divergence angle and beam size of the laser are effectively reduced using a self-focusing lens. This can improve laser power density and solve the randomness problem of the PD detector. It is crucial to realize the quantitative detection of optical detection system feedback and improve the effectiveness of the optical path continuity testing.
