英文摘要:
In this work a Tm3+-doped fluoride glass with good thermal stability is prepared. Intensive 1.8 and 2.3 mu m emissions are obtained when pumped by an 800 nm laser diode. And the 1.48 mu m emission is limited because of the much strong radiation around 1.8 mu m. On the basis of absorption spectrum, radiative properties are investigated and discussed according to Judd-Ofelt parameters (Omega(2), Omega(4), Omega(6)) calculated by Judd-Ofelt theory. Besides, absorption and emission cross-sections of (3) F (4) -> (3) H (6) transition are figured out and analyzed by using McCumber and Beer-Lambert theories. The high gain around 1.8 mu m was predicted by the large sigma(emi)tau(rad) product (29.8 x 10(-21) cm(2) ms). The results obtained indicate that the Tm3+-doped fluoride glass can be a promising 2.0 mu m laser glass material.
