Thermal Lensing Spectroscopy With Picosecond Pulse Trains and a New Dual Beam Configuration [PDF]
, 1982 In this communication, we wish to report on the use of synchronously mode-locked picosecond lasers in a pump-probe configuration for TL spectroscopy. The peak power for these picosecond lasers is very high and, of course, the fundamental of the dye laser

Sub-picosecond thermalization dynamics in condensation of strongly coupled lattice plasmons [PDF]
Nature Communications, 2019 Bosonic condensates offer exciting prospects for studies of non-equilibrium quantum dynamics. Understanding the dynamics is particularly challenging in the sub-picosecond timescales typical for room temperature luminous driven-dissipative condensates ...

Beating of exciton-dressed states in a single semiconductor InGaAs/GaAs quantum dot [PDF]
, 2009 We report picosecond control of excitonic dressed states in a single semiconductor quantum dot. A strong laser pulse couples the exciton and biexciton states, to form an Autler-Townes doublet of the neutral exciton transition.
