摘要: PROBLEM TO BE SOLVED: To equalize respective optical output characteristics of a plurality light emitting sections in surface laser array with time. SOLUTION: The 100 includes first current section which mesa shape and passing region constriction structure are rectangular, second rectangular circular. is less aging than the section. arranged at center portion two dimensional greater temperature rise, periphery rise. Accordingly, substantially equalizes irrespective time elapsed, even if has uneven distribution plane thereof. COPYRIGHT: (C)2009,JPO&INPIT
