:* Interestingly the orange appears at only narrow green wavelength, but we get a lot more fluorescence when the crystal is warm
:*Transitions appear to be right where they are supposed to be from the literature. We expect it at 527.5381nm at see very bright fluorescence at 1055.0775/2=527.53875nm. Also see some orange in the vicinity of the adjacent site's peak at 527.6426nm.
:*Wavemeter and spectrum analyzer give different peaks. 1055.0818 on the wavemeter is 1055.004 on the optical spectrum analyzer. OSA seems to be off by about 0.08nm.
:* If you pull out the transfer line when the cryostat is cold, it warms up pretty slowly, might be able to use to take measurements as fn of temp
:* There is also evidence of absorption but it's not very good at this point. The green transmission is more like a a pulse train than a constant output, this needs to be fixed/addressed. SHG seems to make variations in cavity transmission much worse; i suppose it sort of squares them. Hopefully we can get the output more constant.
