Title (EN) LASER BEAM SYNTHESIZING DEVICE
(FR) DISPOSITIF DE SYNTHÈ DE FAISCEAU LASER
(JA) レーザビーム合成装置
Abstract:
(EN) A laser beam synthesizing device (10) is provided with an emission optical system (20) for emitting a plurality of circular laser beams IL propagated coaxially and having mutually different wavelengths, and a concentric circular diffracting optical element (30) for diffracting the plurality of circular laser beams IL, the diffracting optical element (30) diffracting the plurality of circular laser beams in accordance with the wavelength thereof so that the local diffraction angles of diffracted light DL of the plurality of circular laser beams IL incident at mutually different local incidence angles are equal to each other.
(FR) Un dispositif de synthèse de faisceau laser (10) est pourvu d'un système optique d'émission (20) pour émettre une pluralité de faisceaux laser circulaires IL propagés de manière coaxiale et ayant des longueurs d'onde mutuellement différentes, et un élément optique de diffraction circulaire concentrique (30) pour diffracter la pluralité de faisceaux laser circulaires IL, l'élément optique de diffraction (30) diffractant la pluralité de faisceaux laser circulaires en fonction de la longueur d'onde de ceux-ci de telle sorte que les angles de diffraction locaux de la lumière diffractée DL de la pluralité de faisceaux laser circulaires IL incidents à des angles d'incidence locaux mutuellement différents sont égaux les uns aux autres.
(JA) レーザビーム合成装置(10)は、同軸で伝搬し、且つ、波長が互いに異なる複数の円環レーザビームILを出射する出射光学系(20)と、複数の前記円環レーザビームILを回折する同心円状の回折光学素子(30)と、を備え、前記回折光学素子(30)は、互いに異なる局所入射角で入射する複数の前記円環レーザビームILの回折光DLの局所回折角が互いに等しくなるように前記波長に応じて複数の前記円環レーザビームを回折させる。
