Cím: Stimulated emission, multiphoton processes and attosecond science viewed
from a historical perspective

Időpont: 2017. szeptember 15. 10 óra
Helyszín: ELI-ALPS, Szeged, Budapesti út 5.

Absztrakt:
The process of stimulated emission of radiation will be discussed, first in
the context of black-body radiation, as it appeared more than hundred years
ago in the works of Planck and Einstein. Later results concerning negative
absorption, amplification and laser action will also be reviewed, including
multiphoton processes which take place during the interaction of very-large-
intensity lasers with various constituents of matter. These high-order
processes result in large spectral broadening, and may lead to extreme
temporal localization of the signals, thus yielding e.g. attosecond light
pulses. The development of theoretical methods, interpretations and some
examples of basic experimental achievements will be analysed. At the centenary
of the first publications on the concept of stimulated emission, we attempt to
build a bridge between the early thoughts and recent studies of attosecond and
strong-field science.
