Room-temperature cw lasing at 1.063 ..mu..m was obtained in Nd(Al,Cr)/sub 3/(BO/sub 3/)/sub 4/ crystals. Cross pumping via Cr/sup 3 +/ is as efficient as direct pumping via Nd/sup 3 +/. Thresholds around 20 mW and slope efficiencies up to 13% have been measured. The internal losses were high, around 15%, which we ascribed to imperfect crystal quality. Improvement of crystal quality should lead to thresholds in the mW range.
