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 15):
Method for generating laser pulses by non-linear four-wave mixing, comprising the steps of:\n generating a pump beam of femtosecond laser pulses at a pump wavelength; temporally stretching the laser pulses of the pump beam; providing the stretched laser pulses of the pump beam to a non-linear optical medium to produce a signal beam at a signal wavelength by four-wave mixing in the non-linear optical medium.
