Abstract:

We present the design of the in-vacuum optical parametrical oscillator (VOPO) to be used in aLIGO squeezing experiments.

T2000273 describes the OPO parameters used in O3.

Notes and Changes:

The characteristics of the OPO M1 mirror that has been in operation in O3 is now described in T2000273 (this is related to E1800193).

For O4 M1 and M2 will be swapped, changes described in E2000155
