Claim 8:
9. The laser light providing module according to claim 8,
wherein the laser light providing module includes a module carrier configured for carrying the laser chip package structure, the optical lens and the beam quantity adjuster, and the laser chip package structure, the optical lens and the beam quantity adjuster are integrated into a single optical component by the module carrier;
wherein the laser chip package structure includes a package casing, two conductive pins partially exposed from the package casing, and a laser light-emitting diode chip disposed inside the package casing;
wherein the beam quantity adjuster is a spatial light modulator or a beam distribution element having at least two through openings;
wherein, when the beam quantity adjuster is the beam distribution element, the optical lens is configured for parallelly guiding the laser beam to project onto the at least two through openings, so that the at least two through openings are completely covered by the laser beam;
wherein, when the beam quantity adjuster is the beam distribution element, the beam distribution element is configured for allowing a part of the laser beam to pass through the at least two through openings so as to correspondingly form at least two projection beams, and a shortest distance between the at least two through openings is equal to a shortest distance between the at least two projection beams;
wherein, when the beam quantity adjuster is the beam distribution element, a size and a shape of a light spot projected by the projection beam on an active region of the photodiode are respectively changed according to a size and a shape of the through opening of the beam distribution element;
wherein, when the beam quantity adjuster is the spatial light modulator, the spatial light modulator is configured for allowing the laser beam to pass through or for reflecting the laser beam, thereby converting the laser beam into the at least two projection beams, and the spatial light modulator is configured for adjusting the shortest distance between the two projection beams, a quantity of the projection beams, and the size and the shape of the light spot of the projection beam.
