摘要: A rate equation approach is used to model an experimentally realized ~ 2 mum Tm3+-doped tellurite fiber laser utilizing in-band pumping scheme (3H6 rarr 3F4) . Excellent agreement between the theoretically predicted and measured slope efficiency obtained. It shown that in order achieve thresholds it important include cross-relaxation mechanisms with 3H4 level, even scheme. By fitting results of level lifetime measurements threshold pump powers we have extracted parameters Tm-doped glass.
