摘要：

Er3+-doped tellurite singlemode fibre is fabricated and signal amplification and laser oscillation are demonstrated for the first time. A small-signal gain of 16dB at 1560nm is obtained for a pump power of 130mW at 978nm. A laser oscillation is observed with a threshold pump power of 120mW at 978nm and a slope efficiency of 0.65% using this fibre.
