Abstract
An efficient, flashlamp pumped, Nd:YAG laser operating on the 4F3/2 to 4I9/2 transition at 0.946 μm was demonstrated and compared with operation on the 4F3/2 to 4I11/2 transition at 1.064 μm. It is shown that a limiting feature of this laser is amplified spontaneous emission, especially at the strong 1.064 μm transition. A simple but physically significant model is developed which characterizes amplified spontaneous emission and energy storage efficiency well.
