Background technology
Along with the development of social demand, in the field such as laser display and laser processing, be to launch high power (tens watts even near hectowatt) and intensity distributions is even and the angle of divergence is little high quality beam to the requirement of LASER Light Source.But in prior art, be difficult to realize the high-power output of single LASER Light Source, taking semiconductor laser as example, its single power output only has hundreds of milliwatt, therefore, realize high-power output, must carry out multiple laser coupling integrations.So, in limited space, realize the high-power integrated of multiple diode lasers (LD), take into account heat dissipation problem becomes a study hotspot of laser application simultaneously.
Publication number be CN102520524A's " a kind of high-power semiconductor laser source system for laser processing " thus patent adopts the folded battle array of laser by arranging after speculum forms folded light beam and realize high-power output through shaping lens group shaping on height and position separately, but the shortcoming of this design is to be used for that different wavelengths of light is integrated, space availability ratio is low, heat generation density is high, be not easy to heat radiation etc.Publication number is that CN201886268U's " a kind of laser light-source device for Projection Display " patent adopts the speculum group being installed on stairstepping reflector mount to reject no light zone, recycling two closes look eyeglass the light beam of red, blueness and green laser is combined into white light, but due to the requirement of the size of laser own and radiator structure, there is the problems such as ladder reflecting prism frame space availability ratio is low, coupling efficiency is poor in this scheme.
Summary of the invention
The present invention, in order to solve the problem that system radiating is poor, integration mode is single and space availability ratio is low of existing high power integrated laser light source, provides a kind of high power integrated laser light source.
The present invention adopts following technical scheme to realize: a kind of high power integrated laser light source, comprises and close bundle optically coupled device; The arranged on left and right sides symmetry of closing bundle optically coupled device is vertically provided with and is fixed with first heat sink (so-called heat sink with the first laser integration module of collimating lens combination, the temperature that refers to it is not with being delivered to its size variation of heat energy, and it can be the object such as atmosphere, the earth; Industrially refer to miniature water-cooled fin, be used for the device of cool electronic chip), the upper horizontal of closing bundle optically coupled device is provided with the support that is fixed with plus lens; Described close bundle optically coupled device comprise for by the first laser integration module through collimating lens combine that the laser beam that sends reflects or transmission after vertically inject the first filming glass combination on plus lens.When work, be arranged in and close the laser beam that the first laser integration module of bundle optically coupled device arranged on left and right sides sends realize the integrated of laser by vertically injecting plus lens after closing the reflection of bundle optically coupled device or transmission after collimating lens combination collimation.
It is the technology that those skilled in the art easily realize that described the first laser integration module, collimating lens combine, close bundle optically coupled device.
Coupling device volume of the present invention is little, adopts staggered form segmentation minute surface arrangement, and utilizes segmented reflective transmission film technology, has effectively rejected no light zone, improves light source space utilance; Adopt reflection and transmission membrane technology, in conjunction with the three-dimensional arrangement of LASER Light Source, make can to realize multiple beam on light source exit facet and superpose with region, thereby ensure little optical extend, improved the power density of emergent light; Laser integration module can be according to the quantity of power demand expanding laser, thereby it is integrated to realize high power; Laser integration module adopts space multistory setting, and each LASER Light Source has larger heat-dissipating space, can effectively lower heat dissipation design requirement.
