Abstract
Using a 3.1-μm optical parametric chirped-pulse amplifier (OPCPA), we generate a supercontinuum in a step-index chalcogenide fiber that spans from 1.6 to 5.9 μm at the points. The rugged step-index geometry allows for long-term operation, while the spectral bandwidth is limited by the transmission of the fiber.
