“…By careful design of the pulse shape, the pump energy during buildup time can be minimized and back-conversion can be practically eliminated. Previous work on tailoring the pump pulse shape has been shown in [2] for an optical parametric amplifier. Adaptive pump pulse shaping in an OPO has been shown in [3] with the objective of decreasing nonlinear effects in the fiber pump laser by decreasing the peak pulse power and to shape the temporal and spectral output of the OPO.…”

The conversion efficiency of an optical parametric oscillator is reduced by energy consumption during build-up of signal and idler intensities and due to back-conversion effects. By tailoring the pump pulse temporal shape, we are able to improve the conversion efficiency by minimizing build-up time and back-conversion. Simulations predict a significant improvement in 1064 nm to 4000 nm idler conversion by using a double-rectangular temporal shape rather than using a simple Gaussian pulse. Experimental results qualitatively verify the effect resulting in a 20% improvement of a rectangular pulse over a Gaussian pulse.
