Title (EN) METHOD AND APPARATUS FOR COMBINING LIGHT SOURCES IN A PUMP LASER ARRAY
(FR) PROCÉDÉ ET APPAREIL POUR COMBINER DES SOURCES DE LUMIÈRE DANS UN RÉSEAU LASER DE POMPAGE
Abstract:
(EN) An apparatus for providing pump light (50) of a first wavelength λ1 to a laser (32) that emits a second wavelength λ2 has first and second lasers (12a, b) of the wavelength λΐ to direct light along first and second axes (A,B) in a first direction. The first and second axes define a first plane PI. To form a composite light beam (50) of wavelength λ1, a filter apparatus (40) has a first filter (Fl) on a first surface (36) at an oblique angle to the first and second axes (A,B) and that transmits λΐ and reflects λ2. A second filter (F2) on a second surface (54) parallel to the first surface (36), reflects λΐ and transmits λ2. A third filter (F3) formed on the first surface (36) coplanar with the first filter (Fl) reflects λΐ and transmits λ2. The filter apparatus (40) re-aligns the first and second axes (A,B) along a second plane P2, orthogonal to P 1 and parallel to the first direction and prevents feedback from the pumped laser (32) to the first and second lasers (12a, b).
(FR) L'invention concerne un appareil pour fournir une lumière de pompage (50) d'une première longueur d'onde λ1 à un laser (32) qui émet une seconde longueur d'onde λ2, lequel appareil comprend des premier et second lasers (12a, b) de la longueur d'onde λ1 pour diriger de la lumière le long des premier et second axes (A, B) dans une première direction. Les premier et second axes définissent un premier plan PI. Pour former un faisceau de lumière composite (50) de longueur d'onde λ1, un appareil de filtre (40) comprend un premier filtre (F1) sur une première surface (36) à un angle oblique par rapport aux premier et second axes (A, B) et qui émet λ1 et réfléchit λ2. Un deuxième filtre (F2) situé sur une seconde surface (54) parallèle à la première surface (36) réfléchit λ1 et émet λ2. Un troisième filtre (F3) formé sur la première surface (36) coplanaire avec le premier filtre (F1) réfléchit λ1 et émet λ2. L'appareil de filtre (40) réaligne les premier et second axes (A, B) le long d'un second plan P2, orthogonal à P1 et parallèle à la première direction, et empêche une rétroaction du laser pompé (32) sur les premier et second lasers (12a, b).
