  • Method and device for cavity enhanced optical vernier spectroscopy
    Patent number: 8120773
    Abstract: A spectroscopic analysis of a sample includes arranging the sample in a resonator cavity for transmitting cavity mode frequencies with a cavity mode frequency spacing, coupling pulsed source light into the resonator cavity, with the source light including source comb frequencies with a source frequency spacing, coupling pulsed transmitted light out of the resonator cavity, and spectrally resolved detecting the transmitted light with a detector device. The cavity mode frequency spacing and the source frequency spacing are detuned relative to each other, so that the transmitted light includes transmitted comb frequencies with a spacing larger than the source frequency spacing. The detecting feature includes collecting spectral distributions of the transmitted light in dependence on relative positions of the cavity mode frequencies and the source comb frequencies.

  • Method and radiation source for generating pulsed coherent radiation
    Patent number: 7672342
    Abstract: A method of generating pulsed coherent radiation, comprises the step of generating high harmonic pulses by an interaction of laser light pulses with a non-linear medium contained in a resonant cavity, wherein the non-linear medium is arranged in an environment of reduced pressure. Furthermore, a radiation source of generating pulsed coherent radiation is described, comprising a laser pulse source for generating laser light pulses, a resonant cavity including a non-linear medium for generating high harmonic pulses by an interaction of the laser light pulses with the non-linear medium, wherein the non-linear medium is arranged in an environment of reduced pressure.
