Abstract

Tm-doped ZBLAN and Tm-doped silicate glass are compared spectroscopically and the fiber lasing of the Tm 3F43H6 transition around 1.9 µm in ZBLAN and silicate glass is compared. The spectroscopy of these materials indicates that Tm:ZBLAN possesses advantages over Tm:silicate glass due to the lower phonon energies. Diode-pumped fiber lasing experiments demonstrate that Tm:ZBLAN possesses advantages over Tm:silicate in laser performance.
