Ahh.. I was just reading the other day about how BBO and LBO crystals
were hygroscopic, but BiBO is not. Interesting stuff. The model number
is LSR473NL. I have no idea how many TECs are inside the head because
I DID NOT TAKE IT APART!!!! LOL
I am guessing the only TEC is on the 808nm pump diode itself though, because
the LSR-PS-I driver only has 2 CC'd outputs.. one for the LD and one for the TEC.
