CAVITY-ENHANCED ULTRAFAST SPECTROSCOPY: ULTRAFAST MEETS ULTRASENSITIVE
Proceedings of the 71st International Symposium on Molecular Spectroscopy, 2016 Ultrafast optical spectroscopy methods, such as transient absorption spectroscopy and 2D spectroscopy, are widely used across many disciplines. However, these techniques are typically restricted to optically thick samples, such as solids and liquid solutions.

A difference detection system for high precision measurements of ultrafast transmission changes [PDF]
, 1985 Ultrafast transmission changes can be recorded with high precision by means of a difference detection system. Using single pulses of low energy (0.1 nJ) and low repetition rate, variations of the transmitted energy induced by an excitation pulse are ...

Ultrafast Photodynamics of Glucose [PDF]
The Journal of Physical Chemistry B, 2017 We have investigated the photodynamics of $β$-D-glucose employing our field-induced surface hopping method (FISH), which allows us to simulate the coupled electron-nuclear dynamics, including explicitly nonadiabatic effects and light-induced excitation.

Numerical method for nonlinear optical spectroscopies: Ultrafast ultrafast spectroscopy [PDF]
The Journal of Chemical Physics, 2019 We outline a novel numerical method, called Ultrafast Ultrafast (UF2) spectroscopy, for calculating the nth-order wavepackets required for calculating n-wave mixing signals. The method is simple to implement, and we demonstrate that it is computationally more efficient than other methods in a wide range of use cases. The resulting spectra are identical

An ultrafast algorithm for ultrafast time-resolved coherent Raman spectroscopy [PDF]
Communications ChemistryTime-resolved coherent Raman spectroscopy (CRS) is a powerful non-linear optical technique for quantitative, in-situ analysis of chemically reacting flows, offering unparalleled accuracy and exceptional spatiotemporal resolution. Its application to large polyatomic molecules, crucial for understanding reaction dynamics, has thus far been limited by the
