Passively mode-locked slow pump optical parametric oscillators.
We predict that employing a Bragg grating to simultaneously phase match and induce large temporal walk-off between the signal and slow propagating pump in a nonlinear crystal can be conducive to development of passively mode locked optical parametric oscillators in which cw near-infrared pump is efficiently converted into short middle-infrared pulses.
