10 April 1995 Frequency doubling of narrowband high-energy optical parametric oscillators
Author Affiliations +
Poor beam propagation is a typical characteristic of most pulsed optical parametric oscillators. We describe the design and operation of a tunable narrow linewidth (< 0.2 cm-1) high energy (> 100 mJ), low divergence (< 0.5 mrad) OPO system to overcome this problem. Frequency doubling efficiencies of this OPO are 185 when using BBO and 28% in KDP. These high efficiencies are attributed to the use of an unstable resonator in the OPO.
