Mid-infrared fiber optical parametric oscillator using a three- hole suspended-core chalcogenide fiber

摘要

Abstract. A three-hole As2S5 suspended-core fiber with a zero-dispersion wavelength of 2 m is proposed to construct a mid-infrared (MIR) fiber optical parametric oscillator (FOPO). The numerical model of the MIR FOPO is established and a tuning range from 2 to 5 m for the idler light is predicted. 1. Introduction Mid-infrared (MIR) lasers are of great interest due to their various applications in spectroscopy, medicine, and military. However, the output wavelength range of a conventional MIR .
