Abstract

This work reports the intense emission at 2.7 μm in a Er 3 + / Pr 3 + -codoped fluorophosphate (FP) host glass. This FP glass shows good thermal stability and high transmittance around 3 μm . The emission characteristic and energy transfer upon excitation of a conventional 980 nm laser diode are investigated. The prepared glass possesses higher spontaneous transition probability ( 22.16 s 1 ) along with a larger calculated emission cross section ( 6.57 ± 0.11 ) × 10 21 cm 2 corresponding to the laser transition I 4 11 / 2 I 4 13 / 2 . In addition, the effect of Pr 3 + codoping on the 2.7 μm photoluminescence in FP glass is demonstrated. Hence, the advantageous spectroscopic characteristics of Er 3 + / Pr 3 + -codoped FP glass together with the outstanding thermal property indicate that this kind of glass may become an attractive host for developing solid-state lasers at around 2.7 μm .
