Abstract
(DE)
Die Erfindung betrifft eine Lichtaussendevorrichtung (100; 200; 300), mit einer Laserlichteinrichtung (110; 210; 310), welche dazu ausgebildet ist, eine Vielzahl von Laserlichtstrahlen auszusenden, wobei sich Elliptizitäten von Strahlquerschnitten der Laserlichtstrahlen zumindest teilweise voneinander unterscheiden; einer Strahlformeinrichtung (120; 220; 320), welche in den Strahlengang zumindest eines der Laserlichtstrahlen eingebracht ist, und dazu ausgebildet ist, die Elliptizitäten der Strahlquerschnitte der Laserlichtstrahlen aneinander anzugleichen; und einer Strahlkombiniereinrichtung (130; 230; 330), welche dazu ausgebildet ist, die Laserlichtstrahlen nach Angleichen der Elliptizitäten der Strahlquerschnitte durch die Strahlformeinrichtung (120; 220; 320) zu einem Gesamtlichtstrahl zu kombinieren.
(EN)
The invention relates to a light-emitting device (100; 200; 300), comprising: a laser light apparatus (110; 210; 310), which is designed to emit a plurality of laser light beams, at least some ellipticities of beam cross-sections of the laser light beams differing from one another; a beam-forming apparatus (120; 220; 320), which is inserted into the beam path of at least one of the laser light beams and is designed to bring the ellipticities of the beam cross-sections of the laser light beams into line with one another; and a beam-combining apparatus (130; 230; 330), which is designed to combine the laser light beams to form a total light beam after the ellipticities of the beam cross-sections have been brought into line with one another by the beam-forming apparatus (120; 220; 320).
