Abstract

Our novel approach to wavelength-control of a pulsed tunable OPO combines the versatility and wavelength-agility of a grating or etalon with the modularity of injection seeding. We use a wavelength-selective tunable filter (WSTF) external to the OPO cavity, accessing a wider range of wavelengths than with convenient TDL seed sources. The new narrowband tunable OPO system is based on quasiphase-matched (QPM) nonlinear optical media. In summary, a narrowband, ns-pulsed QPM OPO tuned by a wavelength-selective feedback module external to the OPO ring cavity is demonstrated.
