摘要：

High-power free space chaotic laser is generated by a 1530 nm wide-ridged high-power semiconductor lasers (SL) with optical feedback. The multi-transverse-mode output beam result in the suppression of time-delay signature (TDS), eliminating the TDS's interference on the chaotic laser ranging. As the SI. drive current increases, the TDS is gradually suppressed, hut the relaxation oscillation signature is suppressed only in some current range. The current range and corresponding output laser power at different transmission/reflection ratios of beam splitter are investigated in detail. A chaotic laser with average power of 440 mW , the autocorrelation main peak half-height width of 0.07 ns, and the peak side lobe level of -6. 3 dB is generated. This paper provides a chaotic laser source with simple structure, low cost, and high performance for chaotic laser ranging.
