Output power and spectrum of optical parametric generator in the superfluorescent regime.
Explicit expressions for the irradiance and signal spectrum of an optical parametric generator were derived. The calculation is in quantitative agreement with measurements of parametric generators with three different lengths of crystals operating in the superfluorescent regime. The measured spectrum was predicted for the entire measured range up to a gain-length product of 16, and the measured signal power was accurately derived up to a gain-length product of 10.
