Embodiment 2
[0028] Example 2: Such as Picture 9 As shown, the present invention can be applied to a three-chip projection display system. After the six single-primary-density integrated laser light sources 17 are combined by the beam combiner 18, they are converged to the light pipe 12 through the converging lens 11 for shimming. After shimming, the light beam is projected to the DLP, LCD or LCoS imaging unit 14 through the field lens 13 and the TIR prism 19 for image modulation. The three primary color light beams with image information are combined with a color image by the prism 20, and the projection lens 15 is projected onto the screen 16. This embodiment is suitable for laser projectors and laser TVs.

The invention solves the problems of low optical power, low optical power density, poor heat dissipation, serious speckles and the like of a conventional high-power laser light source by the ingenious space arrangement of the reflecting surfaces and a laser transmitter; the outstanding technical effects are obtained; and the integrated laser light source is low in cost and easy to produce and operate.
Description
Technical field [0001] The invention relates to a laser light source, in particular to an integrated laser light source. Background technique [0002] In the fields of high-brightness laser display and high-power laser processing, the requirements for laser light power are increasing, and it is difficult to achieve high-power output of a single laser light source in the prior art. Especially the semiconductor laser, although it has the advantages of small size, high photoelectric conversion efficiency, simple structure, stable operation, etc., due to the low output power, multiple lasers must be coupled and integrated to achieve high power output. Simple array integration will cause defects such as large volume, low optical power density, large scattering angle, and poor heat dissipation characteristics. How to achieve high power, high power density, and small scattering angle laser light source has become one of the difficult problems in the fields of laser display and laser pr...
