AbstractRecent experiments in mid IR frequency conversion have revealed that older Sellmeir models for zinc germanium phosphide are inadequate. Erroneous predictions in phase matching angles based on older refractive index data have resulted in compromised device performance. We have conducted a complete study of the refractive indices of zinc germanium phosphide from 2 to 9 microns and calculated new Sellmeir coefficients. We have used these to explain the results of recent experiments with mid IR optical parametric oscillators. The phase matching calculations based on our new refractive index data predict much more closely the results of several different mid IR frequency conversion experiments.

Spectral Ranges

Optical parametric oscillators are versatile devices for generating a tunable coherent radiation from an incident laser beam. They rely on nonlinear frequency conversion to cover spectral ranges that are poorly or not covered by direct laser emission. This article presents a short overview of the optical parametric oscillators principles of operation, main implementations and related applications.

Fiber-feedback optical parametric oscillators (OPOs) incorporate intracavity fibers to provide a compact high-energy wavelength-tunable laser platform; however, dispersive effects can limit operation to the sub-picosecond regime. In this research article, we modeled pulse propagation through systems of cascaded fibers, incorporating SMF-28 and ultra-high numerical aperture (UHNA) fibers with complementary second-order dispersion coefficients. We found that the pulse duration upon exiting the fiber system is dominated by uncompensated third-order effects, with UHNA7 presenting the best opportunity to realise a cascaded-fiber-feedback OPO.
