Abstract

Many optical metrology applications require light that is both coherent and broadband. Supercontinuum (SC) spanning several wavelength octaves is an obvious candidate for such applications. Optical fibers are a natural platform for SC generation due to the long interaction length of light within the fiber which allows for broad SC which can ultimately be used as a tunable narrowband source. For tunability in the mid-IR regime, YAG fibers are an excellent candidate due to their high transparency, Kerr nonlinearity, and damage threshold. In our work, we study SC in undoped crystalline YAG fibers produced via laser-heated pedestal growth. We use femtosecond pulses to generate SC in fiber, pumping at several wavelengths ranging out to the mid-IR. Studying the power-dependence of SC generation, we use SC width and shape as indicators of mechanisms that generate SC at each pump wavelength.
