SET OF MICROLASERS WITH DIFFERENT TRANSMISSION FREQUENCIES, IMAGING DEVICE AND IMAGE PROJECTION DEVICE USING SAME

摘要

Said set comprises N microchip lasers (21 to 2N) having substantially the same frequency for the laser material relaxation inside their cavities, with N>/=2. The transmission frequencies of the microlasers differ from one another by at least said relaxation frequency. The invention is applicable to medical analysis, to non-destructive control and projection of images using lasers.
