Linear and non-linear response phenomena of molecular systems
... that we look at. For example, in an optical absorption experiment, we apply light (the external perturbation) and we look at the light that comes back from the system (the response). In this particular case both correspond to the same type of perturbation, but this does not have to be the case, we m ...

One way to overcome this is to sympathetically cool the molecular ions together with atomic ions in socalled Coulomb crystals; a technique which has been applied for more than a decade [12, 13].

Similar measurements performed on large effective area fibres gave values of k Nam in the range 1.03 to 1.17 and showed strong variations from one fibre to another [4]. The correction factor is dependent on wavelength and must be characterised as such for each fibre. The ...
