We report what is believed to be the first resonantly pumped laser operation based on Er(3+)-doped disordered double tungstate single crystal. Efficient laser operation of an Er(3+):NaY(WO(4))(2) laser at ∼1609.6 nm was demonstrated with the naturally wideband, ∼20 nm, InGaAsP/InP laser diode pumping at ∼1501 nm. Laser wavelength tunability of ∼34 nm was also demonstrated based on disorder-broadened emission features of Er(3+):NaY(WO(4))(2) single crystal.
我们报告了首例基于掺铒无序双钨酸钇单晶体的共振抽运激光运转。利用自然宽带、约 20nm 的 InGaAsP/InP 激光二极管在约 1501nm 波长处泵浦，实现了在 ∼1609.6nm 波长处的高效铒（3+）：NaY（WO（4））（2）激光运转。基于 Er（3+）：NaY（WO（4））（2）单晶体的宽发射谱线，实现了约 34nm 的激光波长调谐。
