  • Ultrashort pulse laser system having a quickly tunable central wavelength
    Patent number: 11899339
    Abstract: The present invention relates to a system and method for generating wavelength-tunable laser output pulses using parametric processes, wherein a simultaneous and tuned tuning of the pump pulse wavelength and repetition rate ensures a temporal overlap between pump and seed pulses in a parametric gain medium. Based on this parameter coupling, lasers with a wide tunable wavelength range can be obtained, which can be fully fiber-based and which are also suitable for modern nonlinear microscopy or fluorescence microscopy due to a particularly fast response.
    Type: Grant

  • Generation of output laser pulses having a tunable central wavelength
    Patent number: 10761402
    Abstract: In a device for generating output laser pulses having a tunable central wavelength, based on parametric amplification, a laser system is to be provided that has less complexity, but that nevertheless provides great tunability for the wavelength, permits rapid switching of the wavelength, and allows the spectral bandwidth of the emitted pulses to be adjusted. This is attained in that for adjustability of the bandwidth of the output laser pulses, an optical device is provided that is designed to influence the spectral phase of the pump pulses as a function of the spectral phase of the seed pulses.
