All-Normal-Dispersion Mode-Locked Fiber Laser With a Tunable Angle-Spliced Polarization-Maintaining Fiber Lyot Filter

IEEE Photonics Journal, 2021
We have proposed and implemented an all-polarization-maintaining mode-locked fiber laser operating in all-normal-dispersion regime based on nonlinear amplifying loop mirror.

Thermometry and signatures of strong correlations from Raman spectroscopy of fermionic atoms in optical lattices [PDF]

, 2009
We propose a method to directly measure the temperature of a gas of weakly interacting fermionic atoms loaded into an optical lattice. This technique relies on Raman spectroscopy and is applicable to experimentally relevant temperature regimes ...

Optical Spectroscopy of Type Ia Supernovae [PDF]

, 2008
We present 432 low-dispersion optical spectra of 32 Type Ia supernovae (SNe Ia) that also have well-calibrated light curves. The coverage ranges from 6 epochs to 36 epochs of spectroscopy.

Mid-infrared and optical spectroscopy of ultraluminous infrared galaxies: A comparison [PDF]

, 1999
New tools from Infrared Space Observatory (ISO) mid-infrared spectroscopy have recently become available to determine the power sources of dust-obscured ultraluminous infrared galaxies (ULIRGs).

Spatial probabilistic mapping of metabolite ensembles in mass spectrometry imaging

Nature Communications, 2023
Spatial visualization of metabolites in tissues via mass spectrometry imaging can be prone to user perception bias. Here, the authors report the computational framework moleculaR that introduces probabilistic data-dependent molecular mapping of nonrandom

Simulation of optical response functions in molecular junctions

, 2016
We discuss theoretical approaches to nonlinear optical spectroscopy of molecular junctions. Optical response functions are derived in the form convenient for implementation of Green function techniques, and their expressions in terms of pseudoparticle ...

High-precision spectroscopy of ultracold molecules in an optical lattice [PDF]

, 2015
The study of ultracold molecules tightly trapped in an optical lattice can expand the frontier of precision measurement and spectroscopy, and provide a deeper insight into molecular and fundamental physics. Here we create, probe, and image microkelvin $^{

Self-normalizing phase measurement in multimode terahertz spectroscopy based on photomixing of three lasers

, 2014
Photomixing of two near-infrared lasers is well established for continuous-wave terahertz spectroscopy. Photomixing of three lasers allows us to measure at three terahertz frequencies simultaneously.
