Abstract :
We report on the observation of second-harmonic generation in epitaxial Gd/sub x/Y/sub 1-x/Ca/sub 4/O(BO/sub 3/)/sub 3/ thin films with atomically smooth surfaces. Those films exhibit the noncritical phase-matching second-harmonic generation of neodymium-doped yttrium aluminum garnet lasers at room temperature.
