Abstract

A high-power diode-cladding-pumped Ho3+, Pr -doped fluoride glass fiber laser is demonstrated. The laser produced a maximum output power of 2.5 W at a slope efficiency of 32% using diode lasers emitting at 1150 nm. The long-emission wavelength of 2.94 μm measured at maximum pump power, which is particularly suited to medical applications, indicates that tailoring of the proportion of Pr3+ ions can provide specific emission wavelengths while providing sufficient de-excitation of the lower laser level.
