ULTRASHORT PULSE LASER SYSTEM HAVING A QUICKLY TUNABLE CENTRAL WAVELENGTH

摘要

The invention relates to a system and to a method for producing wavelength-tunable laser output pulses using parametric processes, wherein a time overlap between pump pulses and seed pulses in a parametric amplification medium is ensured by means of a simultaneous and coordinated detuning of the pump pulse wavelength and of the pump pulse repetition rate. On the basis of this parameter coupling, lasers having a widely tunable wavelength range can be obtained, which lasers can be completely fiber-based and are also suitable for modern nonlinear microscopy or fluorescence microscopy by virtue of particularly quick response behavior.
