In-line optical subtraction using a differential Faraday rotation spectrometer for 15NO/14NO isotopic analysis
Eric J. Zhang, Daniel M. Sigman, Gerard Wysocki
We present a dual-modulation Faraday rotation spectrometer with in-line optical subtraction for differential measurement of nitric oxide (NO) isotopologues. In-situ sample referenc…
Terahertz hyperspectral imaging with dual chip-scale combs
Lukasz A. Sterczewski, Jonas Westberg, Yang Yang +4
Hyperspectral imaging is a technique that allows for the creation of multi-color images. At terahertz wavelengths, it has emerged as a prominent tool for a number of applications,…
Mid-infrared dual-comb spectroscopy with low drive-power on-chip sources
Lukasz A. Sterczewski, Jonas Westberg, Mahmood Bagheri +9
Two semiconductor optical frequency combs consuming less than 1 W of electrical power are used to demonstrate high-sensitivity mid-infrared dual-comb spectroscopy in the important…
Cavity attenuated phase shift Faraday rotation spectroscopy
Link Patrick, Jonas Westberg, Gerard Wysocki
Cavity attenuated phase shift Faraday rotation spectroscopy has been developed and demonstrated by oxygen detection near 762 nm. The system incorporates a high-finesse cavity toget…
Computational coherent averaging for free-running dual-comb spectroscopy
Lukasz A. Sterczewski, Jonas Westberg, Gerard Wysocki
Dual-comb spectroscopy is a rapidly developing technique that enables moving parts-free, simultaneously broadband and high-resolution measurements with microseconds of acquisition…
Optical frequency comb Faraday rotation spectroscopy
Alexandra C. Johansson, Jonas Westberg, Gerard Wysocki +1
We demonstrate optical frequency comb Faraday rotation spectroscopy (OFC-FRS) for broadband interference-free detection of paramagnetic species. The system is based on a femtosecon…
Multiheterodyne spectroscopy using interband cascade lasers
Lukasz A. Sterczewski, Jonas Westberg, Charles Link Patrick +8
While mid-infrared radiation can be used to identify and quantify numerous chemical species, contemporary broadband mid-IR spectroscopic systems are often hindered by large footpri…
Dual Modulation Faraday Rotation Spectroscopy of HO2
Brian Brumfield, Wenting Sun, Yiguang Ju +1
The technique of dual modulation Faraday rotation spectroscopy has been applied for near shot-noise limited detection of HO2 at the exit of an atmospheric pressure flow reactor. Th…
