Abstract:
The invention relates to an apparatus for generating laser pulses by non-linear four-wave mixing. It is an object of the invention to provide a technique which enables the generation of short laser pulses in the wavelength ranges between 800 nm and 1000 nm or between 1100 nm and 1500 nm based on a four-wave mixing process using a rare earth doped femtosecond laser as a pump source. The apparatus of the invention comprises: a pump laser source to emit a pump beam of femtosecond laser pulses at a pump wavelength; a chirp unit to receive the pump beam from the pump laser source and configured to temporally stretch the laser pulses; and a parametric conversion unit to receive the pump beam from the chirp unit and configured to produce a signal beam at a signal wavelength by four-wave mixing in a non-linear optical medium. Moreover, the invention relates to a method for generating laser pulses by non-linear four-wave mixing.

Claim (Index 3):
Apparatus of  claim 2 , comprising a wavelength shifting unit arranged in the second beam path between the pump laser source and the parametric conversion unit to shift the wavelength of the laser radiation of the idler beam.
