Abstract

We have examined the feasibility of applying laser heated pedastal growth (LHPG) to the preparation of crystal fibers of BaY₂F₈ doped with Yb and Tm in an investigation of the optimization of this system as a visible upconversion laser. Material of sufficient optical quality to perform laser experiments was produced. In preliminary experiments, we have been able to observe room temperature laser operation at 649 nm with chopped 960 nm pumping in a fiber of composition BaYYb_0.99Tm_0.01F₈.
