What is LBO with theta=90, phi=9 used for? I can't find any mention of it anywhere (SHG of 1064 nm has phi=10.7).
SNLO tells me that such a crystal can be used for SHG at around 1500 nm; however, I can't find any references to frequency-doubled Er:Glass lasers, which AFAIK are the only lasers that lase at that wavelength.
