Light source device based on fluorescent crystal pump light waveguide

Abstract

The invention provides a light source device based on a fluorescent crystal pump light waveguide, and relates to the technical field of optics. The light source device based on the fluorescent crystal pump light waveguide comprises a base, a sliding rail is fixedly arranged at the upper end of the base, and a first sliding base, a second sliding base, a third sliding base and a fourth sliding base are arranged at the upper end of the sliding rail in a sliding mode. Locking devices are fixedly arranged on the side portions of the first sliding base, the second sliding base, the third sliding base and the fourth sliding base, two fixing rings are fixedly arranged at the upper end of the first sliding base, and three adjusting bolts are fixedly arranged on each fixing ring. According to the light source device based on the fluorescent crystal pumping light waveguide, light emitted by pumping laser can be converted into low-cost blue-green light, the low-cost blue-green light is converted into yellow-green light for use, and therefore the cost of generating the yellow-green light is effectively reduced, and use is convenient.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to a light source device based on a fluorescent crystal pumped optical waveguide. Background technique [0002] At present, the yellow-green light sources on the market mainly include yellow-green light diodes (LEDs), yellow-green laser diodes (LDs) and larger yellow-green lasers. Although LED products are low in cost, they have low intensity and often cannot meet the needs of projection display or medical applications. However, LD products are expensive, low in efficiency, and the core technology is firmly controlled by overseas companies. It is currently difficult to apply on a large scale. Yellow-green lasers cannot be used on a large scale due to high operation and maintenance costs. Therefore, it is necessary to develop a new, Low-cost, reliable yellow-green light sources are particularly important. [0003] Compared with the high cost of yellow-green laser diodes, blue laser...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a light source device based on fluorescent crystal pumped optical waveguide, which solves the problem that the cost of yellow-green laser diodes is high, and when using laser-pumped fluorescent light sources to generate yellow-green light, the fluorescent material is not resistant to high temperatures. Under the thermal effect of laser irradiation, it is easy to produce thermal quenching problems, resulting in a decrease in conversion efficiency and a decrease in output power
