一种色散管理呼吸模式锁模半导体环形激光器产生线性下啁啾脉冲，该脉冲被色散补偿到短至185 fs的持续时间，并且其特征在于二次谐波产生频率分辨光学选通。与上啁啾相比，下啁啾由于时间和光谱半导体增益动力学而允许更宽的锁模光谱和更短的脉冲产生。在323-MHz脉冲重复率下测得的平均输出功率为14 mW，这意味着峰值功率为/spl sim/230 W，聚焦强度为/spl sim/4.6 GW/cm/sup 2/。据我们所知，这是最高的峰值功率和最短的脉冲产生从电泵浦全半导体系统，仅通过线性啁啾补偿获得。
A dispersion-managed breathing-mode mode-locked semiconductor ring laser generates linear down-chirped pulses which are dispersion compensated to duration as short as 185 fs and characterized by second-harmonic generation frequency-resolved optical gating. Down-chirping when compared to up-chirping allows broader mode-locked spectra and shorter pulse generation owing to the temporal and spectral semiconductor gain dynamics. The measured average output power is 14 mW at 323-MHz pulse repetition rate, implying a peak power of /spl sim/230 W, and a focused intensity of /spl sim/4.6 GW/cm/sup 2/. To our knowledge, this is the highest peak power and the shortest pulse generation from an electrically pumped all-semiconductor system, obtained only by linear chirp compensation.
