Abstract[English]
A laser generating apparatus includes a first non-linear crystal disk (20) for transmitting a first beam of photons (L101) having a first frequency to a second beam of photons (L201, L202) having the first frequency and a second frequency oscillating in polarization directions orthogonal to each other, the second frequency being a half of the first frequency. Further included is a waveplate (30) for transmitting the second beam of photons (L201, L202) to a third beam of photons (L301, L302) by rotating polarization directions of the second beam of photons (L201, L202) such that the photons of the first frequency and of the second frequency oscillate in the same polarization directions. A second non-linear crystal disk (40) is configured to transmit the third beam of photons (L301, L302) to a fourth beam of photons (L401, L402, L403) of the first frequency, the second frequency and a third frequency, the third frequency being approximate a third of the first frequency.[French]
Un appareil de génération de laser comprend un premier disque (20) cristallin non linéaire pour transmettre un premier faisceau de photons (LlOl) ayant une première fréquence à un deuxième faisceau de photons (L201, L202) ayant la première fréquence et une deuxième fréquence oscillant dans des directions de polarisation orthogonales l'une à l'autre, la deuxième fréquence étant une moitié de la première fréquence. Est en outre incluse une lame onde (30) pour transmettre le deuxième faisceau de photons (L201, L202) à un troisième faisceau de photons (L301, L302) par rotation de directions de polarisation du deuxième faisceau de photons (L201, L202) de telle sorte que les photons de la première fréquence et de la deuxième fréquence oscillent dans les mêmes directions de polarisation. Un deuxième disque (40) cristallin non linéaire est conçu pour transmettre le troisième faisceau de photons (L301, L302) à un quatrième faisceau de photons (L401, L402, L403) de la première fréquence, de la deuxième fréquence et d'une troisième fréquence, la troisième fréquence étant proche d'un tiers de la première fréquence.
