Fully Stabilized Mid-Infrared Frequency Comb for High-Precision Molecular Spectroscopy [PDF]

, 2016
A fully stabilized mid-infrared optical frequency comb spanning from 2.9 to 3.4 um is described. The comb is based on half-harmonic generation in a femtosecond optical parametric oscillator, which transfers the high phase coherence of a fully stabilized near-infrared Er-doped fiber laser comb to the mid-infrared region.

Mid-infrared spectroscopy of two luminous submillimeter galaxies at z~2.8 [PDF]

Astrophys.J. 625 (2005) L83-L86, 2005
Using the Infrared Spectrograph (IRS) on board the Spitzer Space Telescope, we have obtained rest frame mid-infrared spectroscopy of two bright submillimeter galaxies. SMMJ02399-0136 at z=2.81 shows a superposition of PAH emission features and a mid-infrared continuum, indicating significant and roughly equal contributions to its bolometric luminosity ...
