1. A laser device, comprising:
a substrate including a bottom portion and a side portion that is connected to said bottom portion and that cooperates with said bottom portion to define a receiving space, said bottom portion including a lower sub-portion and a higher sub-portion;
a plurality of laser elements that are disposed on said higher sub-portion of said substrate and that are adapted for emitting laser light rays; and
a light guide member that is disposed on said lower sub-portion of said substrate and that has a plurality of reflection surfaces for reflecting the laser light rays emitted from said laser elements so as to change travelling direction of the laser light rays, said reflection surfaces being inclined with said substrate, and being inclined with each other to respectively face said laser elements in different directions.
