  • Generator of at least three coherent laser beams in the infrared and visible domain
    Patent number: 9690165
    Abstract: According to a first aspect, the invention relates to a generator of at least three coherent laser beams at least one beam of which is in the infrared domain and at least one beam of which is in the visible domain, comprising: an elementary source for emitting a first continuous-wave laser beam, at a first given infrared wavelength; a nonlinear crystal frequency doubler, allowing, from a first beam sampled from the first laser beam at the first wavelength, a second laser beam to be generated at a second wavelength; and a nonlinear crystal sum frequency generator, allowing, from a second beam sampled from the first laser beam at the first wavelength and from the second laser beam at the second wavelength, a third laser beam to be generated at a third wavelength.
