Progress of Squeezed light experiment

Member: Tatsumi. Yuefan

We tested the correspondence between the laser output power and the beam size.Then tested the beam profile to get the exact position of lens.Detail shows in the attachment.

But for now the beam size we got is not small enough for the SHG and the transmittance is a little bit low, so today we will reset the position of all components, add one more lens, mount the SHG and try to get the green light.
