A visible BaB2O4 optical parametric oscillator (OPO) pumped by a single-axial-mode 355-nm source has been demonstrated. An average output power of 140 mW with a signal wave conversion efficiency of 13% and an idler conversion efficiency of 11% for a total conversion efficiency of 24% has been achieved. The oscillator has continuously tuned from 412 nm to 2.55 μm limited by the infrared transmission range of the crystal. Through injection seeding we obtained single-axial-mode OPO operation with a corresponding OPO linewidth of less than 3 GHz.

    Abstract. The strength of the transient parametric scattering in BaTiO[sub 3] is shown to be strongly dependent on the initial conditions of the sample illumination. It is shown that the effect can be explained by a considerable increase of the seeding radiation intensity after pre-exposure of...
