[Erin, Torrey]

I've pulled one AOM out of the 5 contained in this post. This is serial number 1002 and is labelled as such, as seen in the photo.

The max power on each of the four AOM paths on the SHG sled currently is <5 mW of 775 nm light. The spec sheet says the max power density of these AOMs is 5 W/mm^2. Our current solution has a waist of 57 um. This gives an optimistic max power density of 5e-3 W / (57 e-6)^ / (1m/1000mm)^2 = .64 W/mm^2. At the current power levels and this design, we should not be able to damage the AOM (optically at least). The beam diameter is supposed to be in between 200 and 300 um, therefore I will keep it as close to the lens as possible.

I am waiting to meet with Chris Wipf to ask if I can unplug our 4th moku from the cryo experiment, it seems fairly integrated. Going to use our fourth moku to power the AOM RF and lock OFC2. Erin made a power connection onto the ZHL-1-2W+ RF power amplifier since it does not come with one. We will similarly operate at max voltage on the moku with an attenuator at the input of the amplifier to prevent larger than intended signal amplitudes.
