Expérimental et théorique
The goal of this internship is to demonstrate ultra-low power nonlinear mirrors in the mid-IR, supported by the recent results obtained by the host team [1,2]. The experiments will be performed by optical pumping with a tunable, commercial QCL and - time permitting - with an ultra-fast mid-IR OPO. [1] M. Jeannin, JM Manceau, R. Colombelli, Phys. Rev.
