利用Nd（3+）激光器在1061.9nm（4）F（3/2）？（4）I（11/2）沟道）。在588 nm附近的Nd（3+）（4）G（5/2）-（2）G（7/2）能级泵浦时，自和频混频：1/泵浦+ 1/1061.9 = 1/UV，获得1.8%的紫外辐射。UV可调谐性的范围为378-382 nm。我们首次证明了从自差频混频激光器中产生相干红外辐射：1/泵浦-1/1061.9 = 1/IR，在1305-1365 nm范围内获得了0.5%的产额和可调谐性。
We exploited Nd(3+) laser emission at 1061.9 nm ((4)F(3/2)?(4)I(11/2) channel) in a self-chi((2)) active GdAl(3)(BO(3))(4):Nd(3+) laser crystal. UV radiation was obtained from a 1.8% yield from self-sum-frequency mixing: 1/pump + 1/1061.9 = 1/UV, during pumping in the Nd(3+) (4)G(5/2)-(2)G(7/2) levels near 588 nm. The UV tunability had a range of 378-382 nm. We have demonstrated, for the first time to our knowledge, generation of coherent IR radiation from a self-difference-frequency mixing laser: 1/pump - 1/1061.9 = 1/IR. We got a 0.5% yield and tunability in the 1305-1365-nm range.
