Assignee: REFINED LASER SYSTEMS GMBH
Field: Optics (Instruments)
Classification: CPC G  H | IPC G  H

Claim 9:
10. A method for changing the wavelength of laser pulses using an optically parametric gain medium comprising at least the steps of:
a) generation of pump pulses with defined wavelength and defined repetition rate by means of a mode-locked pump pulse generator,
b) generation of seed pulses,
c) superposition of the seed pulses and pump pulses in the optically parametric amplification medium,
wherein in the event of one of the wavelength or the repetition rate of the pump pulse changing, the other one of the wavelength or the repetition rate changes by means of an optically dispersive element simultaneously in such a way that a temporal overlap of the pump pulse and seed pulses in the optically parametric amplification medium is effected.
