Abstract

The disclosure provides a quality detection device for laser source and the quality detection method thereof. The laser source quality detection device comprises: a reflective mirror set located in a range of emitting light from the laser source for receiving light beams from the laser source, and having at least one reflective mirror to reflect the light emitted from the laser source in a profile the same as that of the light emitted from the laser source; and at least one sensor capable of receiving the reflected light out of a predetermined range so as to determine quality of the laser source.

Claims
