| 摘要 |
The invention relates to a module (10) for coupling a laser diode array, including a base (11) for supporting the laser diodes, a network of laser diodes (201) suitable for emitting laser beams, not necessarily at the same wavelength, towards the outside of the base (11). Moreover, the coupling module comprises a Cassegrain optical system, suitable for focussing laser beams emitted by said network of laser diodes and made up of a convex hyperbolic curved mirror (14) and a concave parabolic curved mirror (15), collimators (131) suitable for concentrating laser beams in a preferred direction, a coolant suitable for maintaining said network of laser diodes at a constant temperature and a PCB card suitable for supplying electricity to said network of laser diodes. The invention is particularly advantageous when used in video projection devices. |
