Abstract

We demonstrate the suitability of a simple continuous-wave-pumped transition-metal-ion-doped waveguide as a broadband light source in the wavelength region 600-1000nm for interferometric applications. Spatially coherent (single mode in the confined direction), spectrally broadband 130nm FWHM luminescence with output powers of several hundreds of microwatts is obtained from a Tisapphire planar waveguide with incident pump powers from an Ar-ion laser of up to 1W. This result represents an increase in power by several orders of magnitude from previously reported simple broadband light sources in this wavelength range.
