Abstract
Sapphire (α-Al(2)O(3)), amorphous and polycrystalline Al(2)O(3), tantalum pentoxide Ta(2)O(5) and the sesquioxides Y(2)O(3), Sc(2)O(3), and Lu(2)O(3) are excellent laser hosts due to their very good thermomechanical properties, broad transparency range and ease of doping with active ions. This article reviews recent research towards the realization of active optical films and the demonstration of gain and laser operation in the waveguides produced from these materials. Compound structures in which laser operation has been demonstrated are highlighted together with the applied fabrication techniques, and details of the laser performance are presented.

Abstract
Tantalum pentoxide (Ta(2)O(5)) layers made by ion plating are implanted with a high fluence of keV Ti, Li, and Er ions. The resulting refractive-index profiles are given from the analysis of guided-wave propagation conditions. A comparison with spectrophotometric measurements is presented. All the implanted layers present low losses (extinction coefficient of some 10(-6)) after thermal annealing in air. Ti-implanted layers exhibit an increase in refractive index, whereas Li- and Er-implanted layers present a slight decrease in refractive index. Er-implanted layers present photoluminescent properties.
