Bandwidth and group-velocity effects in nanosecond optical parametric amplifiers and oscillators

I numerically model broad-bandwidth optical parametric oscillation and amplification to explore the influence of pump bandwidth on conversion efficiency, injection seeding, and generated spectra. I also study narrow-bandwidth pumping of broad-bandwidth signal and idler waves. I show that the relative group velocities of the three waves have a critical effect on device performance in all cases and provide physical explanations for this.
