Abstract

Simultaneous tuning of multiple-output wavelengths was achieved in Rhodamine 6G–doped distributed-feedback zirconia waveguide lasers. As many as four separate output wavelengths were observed for a planar zirconia waveguide of $2.2‐\mathit{\mu }\mathrm{m}$ thickness. The laser output wavelengths corresponded to the propagation modes allowed in the planar waveguide. Continuous tuning by variation of the period of the optically generated grating was achieved from 584 to 611 nm.
