摘要：

In this letter, laser operation is demonstrated with a Eu, Yb: KY(WO4)(2) crystal on the 5D(0) -> F-7(4) transition of the Eu3+ ion. When pumping into the F-7(1) -> D-5(1) absorption band by a diode-pumped Nd3+:KGd(WO4)(2)/KTP laser power-scaled at 533.6 nm up to a watt-level, we achieved 2.5 mW of the continuous wave (CW) red output at similar to 702.1 nm. At quasi-CW pumping with a duty cycle of 10%, the peak power of the ms-long pulses arrived at similar to 19 mW, corresponding to a green-to-red conversion efficiency of 0.8%.
