- ought to tune for 210 Hz (in-between powerlines) since 100 Hz is tough to work due to scattering, etc.
|
We can get 1.1 dBvac at 210 Hz.
The first two attachments are the noise budgets for these optimized angles. The third attachment shows squeezing as a function of homodyne angle and SRC detuning at 210 Hz. To stay below -1 dBvac, the homodyne angle must be kept between 88.5 and 89.7 degrees and the SRC detuning must be kept between -0.04 and 0.03 degrees. This corresponds to fixing the SRC length to within a range of 0.07/360 * 1064 nm = 200 pm. |
