| Program | Nonlinear optical conversion of femtosecond pulses is both of great interest from the fundamental point of view as well as a very versatile tool. In particular optical parametric amplifiers (OPA) allow the generation of tailored pulses from the deep UV to the middle IR. If the OPA is not even seeded by a weak signal, it still generates output light due to the amplification of the vacuum fluctuations of the electromagnetic field. We were recently able to "count" the modes of these fluctuations. Advanced OPAs rely on seeding with continua generated in bulk material. In the talk an overview will be given, how we generate pulses at any wavelength from 190 to 5000 nm. The continua not only allow the generation of pulses down to the 5 fs regime, but are also an unprecedented coherent light source for the probing of the ultrafast and not so fast dynamics and kinetics in physical and chemical processes. | |
