Crosstalk Elimination Study of 650 nm Dense Spectral Beam Combining System
In this paper, we established the first crosstalk elimination DSBC experimental system based on 11 650 nm COS (Chip on Submount) single emitters. The final output beam spectral width stabilizes over 10 nm with 11 completely discrete oscillations. Compared to the previous results [1], the new system’s final DSBC efficiency is improved by more than 13%, and the optimization of beam quality factor in the combining direction is close to 4.6%. With the excellent beam quality and stable locked spectrum, it has the potential to be applied in fields like solid-state laser pumping, which has a rather high value.
