Abstract

The invention provides a light source system and laser projection display equipment, which are applied to the field of laser projection display. The light source system comprises an infrared laser light source and a nonlinear optical crystal array, the input end of the nonlinear optical crystal array is connected with the output end of the infrared laser light source, the nonlinear optical crystal array is used for performing frequency conversion on infrared laser generated by the infrared laser light source and then outputting the infrared laser, the infrared laser light source is a pump light source, and the nonlinear optical crystal array comprises at least one nonlinear optical crystal; each nonlinear crystal is used for outputting a single-mode Gaussian beam, the output end of the nonlinear optical crystal array outputs a coaxial visible Gaussian laser beam, and the coaxial visible Gaussian laser beam provides a light source for laser projection display. The light source system is simple in structure, small in size and low in power consumption. And the requirements of high beam quality, low power consumption, extremely simple packaging architecture and low-cost packaging process are fundamentally met.

Description

technical field [0001] The present application relates to the field of laser projection display, and more specifically, to a light source system and laser projection display equipment. Background technique [0002] Laser projection display technology (laser projection display technology, LPDT) is a display technology that uses red (red, R), green (green, G), blue (blue, B) three primary colors (RGB) lasers as light sources, which can be the most realistic It accurately reproduces the rich and bright colors of the objective world, providing more shocking expressiveness. [0003] At present, laser light sources of laser projection display devices mainly include edge-emitting lasers (EEL) and vertical cavity surface emitting lasers (VCSEL). However, this kind of laser light source has a complex structure, high power consumption, large volume, complicated packaging process, and poor beam quality, which makes it difficult to meet the actual needs of portable and wearable laser p...
