研究目的
Investigating the effect of ytterbium-doped fiber position on the output spectrum of a random fiber laser to develop a novel, simple, low-cost, low-coherence, and robust near-infrared supercontinuum generation method.
研究成果
The position of ytterbium-doped fiber in a random fiber laser's cavity significantly affects the output spectrum, facilitating the generation of high-order Stokes and enabling the production of a near-infrared supercontinuum with a 20dB bandwidth exceeding 500nm. This demonstrates the potential of random fiber lasers as a novel method for supercontinuum generation.
