Abstract (en)
[origin: WO2006092509A1] The invention concerns a laser device (1, 13) comprising: a three-level amplifying medium (3) adapted to emit a first laser beam (3) of fundamental wavelength; a four-level amplifying medium (5) adapted to emit a second laser beam (7) of fundamental wavelength; a non-linear crystal (4) adapted to mix the first and second beams and to generate a third beam (14, 15) whereof the frequency is the sum of the frequencies of said first and second laser beams. Said device is characterized in that the three-level amplifying medium (3) and at least the non-linear crystal (4) form a resonant cavity for the first laser beam (6), and the four-level amplifying medium (5) and at least the non-linear crystal (4) form a resonant cavity for the second laser beam (7), the two amplifying media and the non-linear crystal forming a linear cavity.
