Abstract

A study has been carried out of the design and fabrication of mirrors for Optical Parametric Oscillators (OPOs) operating in the mid-infrared using a variety of coating and substrate materials. The major considerations determining the choice of coating materials are refractive index excursion (determines bandwidth of mirror), optical bandgap (multi-photon effects at the pump wavelength), and porosity (adsorbed water causes absorption features in the tuning range of the OPO). The mirror coatings are mostly of quarter wave type design, and have been fabricated from chalcogenides, fluorides and oxides. The mirrors have been evaluated at repetition rates and pulse lengths similar to those encountered in operation of the OPO, at both the pump (1.064 and 2.1 micrometers ) and typical output wavelengths. Damage data has been gathered for a number of mirrors which form part of the OPO cavity. Second Harmonic Generation was observed at 1.064 micrometers in Cleartran ZnS substrates.
