Experimental study demonstrates 1.3 W visible laser emission in Pr3+-doped ZBLAN fiber, highlighting cladding-pumping feasibility for tunable sources.
We have investigated the laser performance and tunability of a highly Pr3+ doped fluoride glass fiber. Absorption and emission properties as well as laser characteristics in different resonator configurations have been studied. We have achieved 1.3 W output power @ 635nm wavelength with a slope efficiency of 30.6% with respect to the incident pump power. Furthermore, to the best of our knowledge, we present results on wavelength tunability with cladding-pumping on a several meter long Pr3+-doped ZBLAN fiber for the first time.
