Using numerical simulation, we investigate the formation of noise-like pulses with an extremely broadband spectrum in passively mode-locked fiber lasers. The mechanism of spectral broadening is due to the Kerr nonlinearity of the fibers making up the laser cavity. It is found that optimization of the nonlinear-dispersion parameters of the fiber cavity can lead to the generation of noise-like pulses with a spectral width exceeding the gain bandwidth by a factor of more than 10.

被动锁模光纤激光器中具有极宽频谱的类噪声脉冲

使用数值模拟,我们研究了在被动锁模光纤激光器中具有极宽频谱的类噪声脉冲的形成。光谱展宽的机理归因于组成激光腔的光纤的Kerr非线性。发现优化光纤腔体的非线性色散参数会导致产生类似噪声的脉冲,其频谱宽度超过增益带宽达十倍以上。
