An Air-spaced Virtually Imaged Phased Array Spectrometer Based on a Mid-Infrared Optical Frequency Comb

Ibrahim Sadiek, Norbert Lang, and Jean-Pierre H. van Helden

Not Accessible

Your library or personal account may give you access

Abstract

We report on the first air-spaced VIPA spectrometer using a mid-infrared frequency comb, which fully resolves the modes of a 250 MHz comb without filtering. The spectrometer is tested by measuring CH4 in nitrocarburizing plasmas.
