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 dif-
ferent 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 accu-
rately derived up to a gain-length product of 10. © 2008 Optical Society of America
