Abstract: A method for generating frequency converted laser radiation is disclosed. The disclosure provides a method enabling generation of a frequency converted wavelength division multiplexed light source that is easy to implement at low cost. Adjustment of the center frequency and the mode spacing in a frequency converted wavelength division multiplexed light source is also disclosed. A related method of use discloses generating pump laser radiation through combination of multiple pump sources in a wavelength division multiplexed arrangement; passing the pump laser radiation through the non-linear medium of a singly resonant, single-frequency optical parametric oscillator, wherein the pump laser radiation is continuous wave or pulsed, wherein the pulse duration in the latter case is longer than the time the optical parametric oscillation requires to reach its steady state; and coupling out the non-resonant idler or signal laser radiation from the optical parametric oscillator as usable frequency converted laser radiation. Moreover, the invention relates to a laser device for carrying out the method of the invention.

Abstract: A method may comprise: generating an optical frequency comb; applying a filter in a first configuration to the generated optical frequency comb to select a first frequency of the optical frequency comb, wherein, in the first configuration, the first frequency aligns with a first pass-band of the filter, and a second frequency of the optical frequency comb does not align with a second pass-band of the filter; altering the filter to a second configuration to shift the first pass-band and the second pass-band to a shifted first pass-band and a shifted second pass-band; and applying the altered filter to the generated optical frequency comb to select the second frequency of the optical frequency comb, wherein the second frequency aligns with the shifted second pass-band of the filter, and the first frequency of the optical frequency comb does not align with the shifted first pass-band of the filter.
