Abstract

Une unité de source de lumière laser comprend : plusieurs premières lentilles convergentes (22) configurées pour condenser la lumière laser émise à partir de chaque diode des plusieurs diodes laser (20) ; un réseau de microlentilles (24A, 24B) disposé sur un côté avant de l'unité de source de lumière laser (10) par rapport aux plusieurs premières lentilles convergentes (22) ; et une deuxième lentille convergente (26) disposée sur le côté avant de l'unité de source de lumière laser (10) par rapport au réseau de microlentilles (24A, 24B). Le réseau de microlentilles (24A, 24B) et la deuxième lentille convergente (26) sont supportés sur un support de lentille commun (60). Le réseau de microlentilles (24A, 24B) est supporté sur le support de lentille (60) par l'intermédiaire d'un support de réseau (64A, 64B). Plusieurs trous débouchants (64Ab, 64Bb) à travers lesquels de la lumière émise à partir des plusieurs premières lentilles convergentes (22) passe sont formés dans le support de réseau (64A, 64B).
