Compact Broadband Light Source Based on Noise-Like Pulses

We report on broadband generation based on noise-like pulse (NLP) fiber lasers at 1.55 μm and 1.06 μm, respectively. The 1.55 μm laser system can generate a broadband spectrum with a 20 dB bandwidth of up to 205 nm, while the 1.06 μm one can achieve a 20 dB bandwidth of 341 nm after amplification and spectral broadening. Simulation results reproduce experimental details and highlight the role of nonlinear effects in achieving broad spectral outputs, underscoring the suitability of NLPs for advanced applications.
