Abstract

An Nd:YAG planar waveguide laser has been fabricated by ultra-low-fluence ( 2 × 10 12 cm 2 ) swift heavy-ion irradiation ( 60 MeV Ar 4 + ions). The appearance of the buried waveguiding has been associated with an increased refractive index layer as a consequence of the ion-induced electronic damage. Continuous-wave laser oscillations at 1064.2 nm have been observed from the waveguide under 808 nm optical excitation, with the absorbed pump power at threshold and laser slope efficiency close to 26 mW and 5.9%, respectively.
