Broadband ultraviolet-visible transient absorption spectroscopy in the nanosecond to microsecond time domain with sub-nanosecond time resolution
B Lang, S Mosquera-Vázquez, D Lovy… - Review of Scientific …, 2013 - pubs.aip.org
A combination of sub-nanosecond photoexcitation and femtosecond supercontinuum
probing is used to extend femtosecond transient absorption spectroscopy into the
nanosecond to microsecond time domain. Employing a passively Q-switched frequency
tripled Nd: YAG laser and determining the jitter of the time delay between excitation and
probe pulses with a high resolution time delay counter on a single-shot basis leads to a time
resolution of 350 ps in picosecond excitation mode. The time overlap of almost an order of …
