To answer a question with a question, wouldn't it be simpler
to do calorimetry on a small fluorescent UV lamp in a aluminum
hole "cavity" immersed in D2O?
IOW, why bother with single frequencies, when the uv lamp
output runs from micron infrared to 180 nm uv?
These folks got tripling of 532 nm Nd:YAG photons in light water.
