摘要：

We have time resolved the nonradiative relaxation from the 4G7/2 manifold to the upper laser level (for λ = 1.06 μm) of Nd3+ in a Nd: YAG crystal. This has been performed by monitoring the onset of gain for the associated 4F3/2−4I11/2 transition following excitation of the 4G7/2 pump band by a 40-psec, 0.53-μm pump pulse. The nonradiative relaxation time was found to be 470 ± 60 psec at room temperature and no shorter than 400 psec at 440 K. © 1990 Optical Society of America.
