Design of an Optical Parametric Oscillator using a BBO partial cylinder for a continuous tunability between 0.4 μm and 0.9 μm

This work describes the different steps of the design of a cylindric Optical Parametric Oscillator. It is based on a BBO nonlinear crystal shaped as a partial cylinder to be pumped by a commercial micro-laser at 0.355 μm for an energetic and sub-nanosecond emission continuously tunable between 0.4 μm and 0.9 μm.
