摘要
We report the generation of transform-limited 4.3-cycle (23 fs) pulses at 1.6 mu m from a degenerate doubly resonant optical parametric oscillator (OPO) pumped by a 1 GHz mode-locked Ti: sapphire laser. A chi((2)) nonlinear envelope equation was used to inform the experimental implementation of intracavity group-delay dispersion compensation, resulting in resonant pulses with a 169 nm full width half-maximum spectral bandwidth, close to the bandwidth predicted by theory.
