摘要：
CW operation of extremely high efficiency has been observed from the 2.024 mum transition of holmium in a Tm : Ho codoped singlemode fluoride fibre laser. By pumping into thulium absorption between 820 and 830 nm, output powers of 250 mW and maximum slope efficiencies of 60% were observed. These results suggest that pump quantum, and photon conversion efficiencies of 150 and 75% respectively, are readily attainable.
