Planar waveguide lasers and structures created by laser ablation - an overview

摘要

The parameters of planar and channel waveguide lasers fabricated by different tech- niques are reviewed. Materials and properties of thin films used for creation of planar waveguide lasers are summarized. The parameters of active and passive planarr waveg- uides created by the method of pulsed laser deposition and problems of laser deposition are described. The aspects of laser generation of planar waveguide lasers, resonators and channel waveguides are presented. The results of our experiments of laser deposition of thin Ti:sapphire layers and thin layers of Nd: YAG and Nd:YAG are briefly discussed.
