Arm length measurement : cavity kick technique |
|
|
| Quote: |
|
I made some attempts to measure the current length of the arm cavities by using the mass-kicking technique.
|
Why not just scan the Green laser to measure the arm lengths instead? The FSR of the arm is ~3.75 MHz and so all you have to do is lock the arm green and then sweep the PZT until the resonance is found at 3.75 MHz.
