We report on wide spectral tunability of a quasi-continuous wave Pr(3+):KY(3)F(10) laser under InGaN laser diode excitation at 445 nm. The total tuning range exceeded 100 nm in the visible spectral range on several intervals between 521 nm and 737 nm. The broadest continuously tunable region of almost 50 nm extended from 688 nm to 737 nm. Furthermore we present what is to the best of our knowledge the first demonstration of continuous wave laser operation in Pr(3+):KY(3)F(10) on three transitions in the green spectral region. The highest output power of 121 mW was achieved at an emission wavelength of 554 nm with a slope efficiency of 27%.
我们报道了在445nm的InGaN激光二极管激发下，准连续波Pr(3+):KY(3)F(10)激光器的宽光谱可调谐性。在521nm至737nm之间的几个区间内，可见光谱范围内的总调谐范围超过100nm。最宽的连续可调谐区域近50nm，从688nm延伸至737nm。此外，据我们所知，我们首次展示了Pr(3+):KY(3)F(10)在绿色光谱区域的三个跃迁上的连续波激光运转。在发射波长为554nm时，实现了121mW的最高输出功率，斜率效率为27%。
