[CThP7G-04] In situ detection of phase mismatching in optical parametric process for vacuum squeezing

*Yoshitaka Taguchi1, Yasuyuki Ozeki1 (1. The University of Tokyo (Japan))

[Presentation Style] Onsite

We propose a method for detecting phase mismatching by using an optical sideband, which imprints a phase shift on the pump light. By measuring this phase shift, phase mismatching can be detected for feedback control.
