1. Device for the production of tuneable picosecond light pulses in the visible spectral range, having a laser system (LS) that emits femtosecond light pulses in the infrared spectral range, and having an optical frequency converter (FC) for converting the wavelengths of the light pulses into the visible spectral range, wherein the wavelength of the light pulses emitted by the laser system (LS) can be tuned, whereby the conversion of the wavelength of the light pulses by means of the frequency converter takes place in such a manner that the wavelength of the light pulses in the visible spectral range can be tuned, whereby an optical stretcher (OS) is provided, by means of which the pulse duration of the frequency-converted light pulses can be increased to at least 1 ps.
