    Abstract: According to an aspect, the invention relates to a frequency conversion cell (10) including: a nonlinear, birefringent crystal (12), characterized by a first phase matching wavelength and having an input surface (121
    A ) for receiving at least one incident beam, an output surface (121
    B ) for emitting at least one frequency-converted beam, and at least two parallel surfaces (120
    A , 120
    B ), different from the input and output surfaces; and means (14, 14
    A ) for applying an external mechanical force onto at least one of said parallel surfaces (120
    A ), referred to as "force application" surface, thus resulting in a variation in the birefringence of the nonlinear crystal. The value of the applied external mechanical force is predetermined such as to obtain the phase matching in the nonlinear crystal at a second phase matching wavelength different from the first phase matching wavelength.

    Abstract: Coherent spectroscopic methods are described, to measure the total phase difference during an extended interrogation interval between the signal delivered by a local oscillator (10) and that given by a quantum system (QS). According to one or more embodiments, the method may comprise reading out at the end of successive interrogation sub-intervals (T i ) intermediate error signals corresponding to the approximate phase difference (Õ) between the phase of the LO signal and that of the quantum system, using coherence preserving measurements; shifting at the end of each interrogation sub-intervals (T i ) the phase of the local oscillator signal, by a known correction value (Õ (i) FB ) so as to avoid that the phase difference approaches the limit of the inversion region; reading out a final phase difference (Õ f ) between the phase of the prestabilized oscillator signal and that of the quantum system using a precise measurement with no restriction on the destruction; reconstructing a total phase difference over the extended interrogation interval, as the sum of the final phase difference (Õ f ) and the opposite of all the applied phase corrections - ˆ‘ i Æ FB i .
