Simulating Ultrafast Transient Absorption Spectra from First Principles using a Time-Dependent Configuration Interaction Probe
Arshad Mehmood, Myles C. Silfies, Andrew S. Durden +2
Transient absorption spectroscopy (TAS) is among the most common ultrafast photochemical experiments, but its interpretation remains challenging. In this work, we present an effici…
Ultrafast internal conversion and photochromism in gas-phase salicylideneaniline
Myles C. Silfies, Arshad Mehmood, Grzegorz Kowzan +3
Salicylidenaniline (SA) is an archetypal system for excited-state intramolecular proton transfer (ESIPT) in non-planar systems. Multiple channels for relaxation involving both the…
Broadband cavity-enhanced ultrafast spectroscopy
Myles C. Silfies, Grzegorz Kowzan, Neomi Lewis +1
Broadband ultrafast optical spectroscopy methods, such as transient absorption spectroscopy and 2D spectroscopy, are widely used to study molecular dynamics. However, these techniq…
Widely tunable cavity-enhanced frequency combs
Myles C. Silfies, Grzegorz Kowzan, Yuning Chen +5
We describe the cavity-enhancement of frequency combs over a wide tuning range of 450-700 nm (> 7900 cm), covering nearly the entire visible spectrum. Tunable visible freque…
Mid-infrared frequency comb with 6.7 W average power based on difference frequency generation
Anthony Catanese, Jay Rutledge, Myles Silfies +6
We report on the development of a high-power mid-infrared frequency comb with 100 MHz repetition rate and 100 fs pulse duration. Difference frequency generation is realized between…
Tunable visible frequency combs from a Yb-fiber-laser-pumped optical parametric oscillator
Yuning Chen, Myles C. Silfies, Grzegorz Kowzan +2
We present a 100 MHz repetition rate Yb-fiber-laser-pumped synchronously pumped optical parametric oscillator (SPOPO) delivering tunable frequency combs covering almost the entire…
mid-infrared frequency comb generation and stabilization with few-cycle pulses
Alexander J. Lind, Abijith Kowligy, Henry Timmers +5
Mid-infrared laser frequency combs are compelling sources for precise and sensitive metrology with applications in molecular spectroscopy and spectro-imaging. The infrared atmosphe…
Dual frequency comb spectroscopy in the molecular fingerprint region
Henry Timmers, Abijith Kowligy, Alex Lind +8
Spectroscopy in the molecular fingerprint spectral region (6.5-20 m) yields critical information on material structure for physical, chemical and biological sciences. Despite de…
