Abstract
In this work an overview of active planar waveguide systems created by various technologies and especially by method of pulsed laser deposition (PLD) is given. Parameters of created planar waveguide lasers are summarized.
Our experiences with laser deposition and characterization of thin films of Ti:sapphire, Nd:YAG and Nd:YAP are presented. For film deposition a KrF excimer laser was used. Film properties were characterized by XRD, mode spectroscopy, and by study of attenuation and luminescence spectra. Films exhibit waveguiding properties. The waveguide losses as low as 1 dB/cm for Ti:sapphire/sapphire and 0.5 dB/cm for Nd:YAP/(0001)sapphire were measured.
