Abstract

Fiber laser sources with narrow linewidths in the short-wave infrared and mid-infrared spectral regions have many defense, commercial, and sensing related applications. To generate wavelengths not produced by commercially available lasers, we introduce a compact design of a hollow core fiber-based optical parametric amplifier (OPA) with flexible phase-matching schemes. An electric field applied to fiber core liquids or gases can induce the required effective second-order nonlinearity. Quasi-phase-matching for efficient frequency conversion can be realized by applying spatially periodic electric fields along the length of the fiber. We investigate fiber-based OPA designs with xenon gas and liquids such as carbon disulfide to determine the viability of these architectures for efficient wavelength conversion and flexibility.
