Broadly-tunable, High-resolution Mid-IR Spectroscopy

Not Accessible

Your library or personal account may give you access

Abstract

We demonstrate automated C2H2 direct absorption spectroscopy using a CW, tunable optical parametric oscillator, with a resolution of <5x10-4 cm-1 at 2 cm-1/min. We improve the resolution substantially by locking to a frequency comb.
