Title: Semiconductor laser element and laser device
Inventor: OKAMURA AYAKA
IPC: H01S5/00
Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To simplify a device structure wherein a plurality of laser lights of different wavelength are used for reduced size. SOLUTION: Stripes 32 and 42 are formed at such position as deviated to either of laser element chips 30 and 40. The chips of two kinds of elements 30 and 40 of different light emission wavelength are almost parallel to their strips 32 and 42, while so allocated as to close to each other. Thus, the light emitting points of elements are close to each other. Since the interval between light emitting points is about 100 μm or less, they can be taken as a single light emitting point. So, the laser lights of different wavelength outputted from the laser elements 30 and 40 can be processed with a single optical system.
