Abstract

See full text

The invention relates to an apparatus for generating laser pulses. It is an object of the invention to provide a method for generating synchronized laser pulse trains at variable wavelengths (e.g., for coherent Raman spectroscopy/microscopy), wherein the switching time for switching between different wavelengths should be in the sub-μs range. For this purpose the apparatus according to the invention comprises

    a pump laser (1), which emits pulsed laser radiation at a specified wavelength,an FDML laser (3), which emits continuous wave laser radiation at a cyclically variable wavelength, anda nonlinear conversion medium (4), in which the pulsed laser radiation of the pump laser (1) and the continuous wave laser radiation of the FDML laser (3) are superposed. In the nonlinear conversion medium (4) the pulsed laser radiation of the pump laser (1) and the continuous wave laser radiation of the FDML laser (3) are converted in an optical parametric process into pulsed laser radiation at a signal wavelength and an idler wavelength that differs therefrom. Furthermore the invention relates to a method for generating laser pulses.
