Abstract

Er- doped YAG and YAP layers were grown by nanosecond (20 ns) and subpicosecond (450 fs) KrF laser ablation under a wide set of deposition conditions. Results of characterization of films crystallinity and luminescence are presented and discussed. Films grown in ns regime were almost amorphous for substrate temperature to Ts ~ 1000 oC, while films grown in subps regime were partly crystalline, even at low Ts. Film crystallinity was also studied after annealing of amorphous layers under vacuum with CO2 and KrF excimer lasers. Luminescence corresponding to Er+3 ions was observed for all samples.
