cw lasing at 1.6 ..mu..m was obtained for the first time in Cr, Yb, Er:fluoroaluminate glass. Double step pumping via Cr/sup 3 +/ and Yb/sup 3 +/ with a krypton laser yields a threshold pump power of 80 mW. Efficient lasing can be expected using glass samples of optimized dopant concentration and improved optical quality.
