Abstract
Extremely wide wavelength tuning ranges of up to ∼300nm around 1.9μm are theoretically predicted in a Tm-doped BaY2F8 crystal, on the basis of near-infrared measurements of emission and absorption cross sections. A tunability interval of 245nm, from 1849nm to 2059nm, has been demonstrated by room-temperature laser experiments using a 8% Tm-doped crystal.
