Abstract

En laserdiode-lyskilde omfatter minst to laserdioder (1, 2). Strålene (3, 4) av diodene (1, 2) kombineres for eksempel ved en polariserende strålekombinator (11) og den kombinerte strålen (8) fokuseres av en linse (19) på en optisk kabel (20). Strålene (3, 4) påvirkes også i lengderetningen til diodenes (1, 2) laserstriper av anamorfe stråleformingsmidler (7, 8; 9, 10) for å redusere lengden av bildet dannet ved enden av fiberen (20) ved en forhåndsbestemt faktor, valgt slik at den numeriske blenderåpningen til den fokuserte strålen (18) i nevnte lengderetning ikke vesentlig overskrider den til den optiske fiberen (20).
