Ultrashort and broadband mid-IR pulses: challenges and solutions
講演概要：
A current challenge is generating bright, coherent and broadband mid-IR laser pulses. I will present various soliton-based techniques where the soliton can become phase-matched in the mid-IR by so-called resonant radiation (dispersive wave formation). For a negative nonlinearity soliton this occurs in bulk media (e.g. quadratic nonlinear crystals), while for a standard positive nonlinearity soliton it requires substantial waveguide dispersion. I will show experiments in lithium niobate (LN), periodically poled LN, and silicon-based CMOS compatible waveguides, all having substantial mid-IR content. Many applications also require ultrashort few-cycle laser pulses, and I will show a new mid-IR external pulse-compression technique.
