Publikováno v: OSA Advanced Photonics Congress (AP) 2020 (IPR, NP, NOMA, Networks, PVLED, PSC, SPPCom, SOF).

We present a 2D spatial mapping of the χ(3) susceptibility of a niobium borophosphate glass after thermal microprinting of a second order nonlinearity. χ(3) reduction is evidenced in the poled areas using coherent Raman imaging.
