Alexander S. Solntsev

Hello Assaf,

Based on my knowledge, at least two years ago 55% was still the record efficiency:

https://www.osapublishing.org/oe/abstract.cfm?uri=oe-19-12-11152

If there were any further developments in the last 2-3 years, at least they don't seem to be citing the above paper.

Best,

Alex

Dear Prof.Assaf Halevy

I have discussed a similar topic right here: .

https://www.researchgate.net/post/What_is_the_best_beam_for_second_harmonic_generation

According to Prof.Aleksandr Aleksandrovsky , the maximum efficiency is about 92%.
