Title (EN) BEAM SHAPING DEVICE AND LASER OSCILLATOR
(FR) DISPOSITIF DE MISE EN FORME DE FAISCEAU ET OSCILLATEUR LASER
(JA) ビーム整形装置、及びレーザ発振器
Abstract:
(EN) This beam shaping device includes a slow-axis collimator (SAC) and a fast-axis collimator (FAC). The SAC is disposed between a LD bar and the FAC. The SAC includes a first incidence surface and a first emission surface. The first incidence surface includes a plurality of incident-side lens surfaces aligned in the slow-axis direction X. Each incident-side lens surface is shaped to protrude outside the SAC in the cross-section perpendicular to the fast-axis direction Y, and to recede inside the SAC in the cross-section perpendicular to the slow-axis direction X. Each of the first incidence surface and the first emission surface has a concentric arc shape with a point on the emission end surface of a light-emitting layer as a center in the cross-section perpendicular to the slow-axis direction X.
(FR) La présente invention concerne un dispositif de mise en forme de faisceau qui inclut un collimateur à axe lent (SAC) et un collimateur à axe rapide (FAC). Le SAC est disposé entre une barre LD et le FAC. Le SAC inclut une première surface d’incidence et une première surface d’émission. La première surface d’incidence inclut une pluralité de surfaces de lentilles du côté incident alignées dans la direction d’axe lent (X). Chaque surface de lentille du côté incident présente une forme en saillie à l’extérieur du SAC dans la section transversale perpendiculaire à la direction d’axe rapide (Y), et en évidement à l’intérieur du SAC dans la section transversale perpendiculaire à la direction d’axe lent (X). La première surface d’incidence et la première surface d’émission présentent chacune une forme d’arc concentrique avec un point sur la surface d’extrémité d’émission d’une couche électroluminescente en tant que centre dans la section transversale perpendiculaire à la direction d’axe lent (X).
(JA) ビーム整形装置は、SAC及びFACを有している。SACは、LDバーとFACとの間に配置されている。SACには、第1の入射面と第1の出射面とが設けられている。第1の入射面は、遅軸方向Xへ並んでいる複数の入射側レンズ面を有している。各入射側レンズ面の形状は、速軸方向Yに直交する断面においてSACの外側へ凸になる形状であり、かつ遅軸方向Xに直交する断面においてSACの内側へ凹になる形状である。第1の入射面及び第1の出射面のそれぞれの形状は、遅軸方向Xに直交する断面において、発光層の出射端面上の点を中心とする同心の円弧状である。
