Abstract
In laser spectroscopy, the interaction of light emitted from
various types of laser sources – tunable or nontunable
in their output frequency – with the atomic or molecular
species of interest is used to probe the sample through a
variety of spectral responses. In order to perform laser
spectroscopy, suitable laser sources must be selected,
which meet the requirements of the chosen spectroscopic
method. This means that the laser has to provide radiation
in the wavelength range of interest, has the appropriate
emission characteristics (lineshape), and has a suitable
energy to perform the measurements. Further requirements
are pulse length (milliseconds to femtoseconds
or continuous wave), repetition rate, and beam profile.
Nowadays, laser radiation can be generated with most
of the required parameters necessary for the respective
spectroscopic application, either directly or by generating
new radiation frequencies by frequency mixing of one or
several laser beams in a nonlinear medium (gas, liquid,
or solid)
