研究目的
Investigating the possibility of achieving such a large spectral broadening of the generated radiation right in the fiber oscillator.
研究成果
The research demonstrates the possibility of generating light pulses with a spectral width several times broader than the gain bandwidth in passively mode-locked fiber lasers. This is achieved through the Kerr nonlinearity of the fiber medium and the use of saturable absorbers with high modulation of nonlinear losses.
研究不足
The study is limited to the analysis of stationary pulses and does not extensively cover nonstationary regimes of oscillation, such as the generation of noiselike pulses, which could offer further spectral broadening.
