Technical field
The present invention relates to a kind of laser system, relate in particular to a kind of super wide temperature, powerful miniature laser module.
Background technology
Along with the development of present science and technology, the applications of laser scope is also in rapid expansion, such as: Medical Instruments, construction account, indication, military affairs, space flight etc.The application of these aspects all requires laser to keep high-power Laser output in super wide temperature range.And laser module in the market can only work in narrower temperature bandwidth, after ambient temperature surpasses 50 degree, laser can't be worked for a long time, the laser module that perhaps works needs large-sized cooling device, this is to some systems removable, simple in structure, and practical operability is not strong.Wide temperature miniature laser module system need to satisfy: 1, the volume of whole module is little; 2, module stable output power in wide temperature range.
Summary of the invention
For defects, the invention provides a kind of wide temperature laser module, it realizes small size module high power output in wide temperature range; Two bundles or the multiple laser of different temperatures bandwidth are used in conjunction with; Improved simultaneously the noise frequency of output beam, when the particular device instrument used, human visual system was insensitive to the perception of the problems such as the fluctuation that brought by laser noise, broken string.
The technical scheme of wide temperature laser module of the present invention is such: it comprises the different laser beam of at least two bundle temperature bandwidth, and two bundle laser beams are through the synthetic a branch of output of the synthetic mirror of light beam, and each laser beam can be regulated respectively.

Optimally, wide temperature laser module peripheral hardware is put housing, and beam outlet is set on the housing.
It comprises at least two bundle temperature bandwidth different laser beams the technical program, and two bundle laser beams are through the synthetic a branch of output of the synthetic mirror of light beam, and each laser beam can be regulated respectively, realizes small size module high power output in wide temperature range; Two bundles or the multiple laser of different temperatures bandwidth are used in conjunction with; Improved simultaneously the noise frequency of output beam.
The every bundle laser beam of the technical program all comprises laserresonator, comprises pumping source, laser crystal, resonator mirror in the laserresonator, and pumping source is single tube LD or LD array; The mode that the LD energy focuses into crystal be direct coupling type or the Lens Coupling formula; The LD pump light is coupled in the laser crystal by condenser lens, and laser crystal is fundamental frequency luminescent crystal and the generation frequency doubled light crystal composition sandwich type or serial from frequency multiplication that produces; Crystal end-face is directly made the chamber mirror, input is coated with fundamental frequency light and frequency doubled light high-reflecting film, the crystal output is coated with fundamental frequency light high-reflecting film and frequency doubled light anti-reflection film, perhaps passing through independently, the chamber mirror forms resonant cavity, crystal end-face plating fundamental frequency light and frequency doubled light anti-reflection film, laser crystal utilizes wider red, green, blue three primary colors in the market by certain phase matching angle cutting, can realize by the different crystal cut direction.
The synthetic mirror of the light beam of the technical program is a kind of thin slice to the polarisation of light sensitivity (or prism), and the laser beam of the different polarization direction of identical wavelength is synthetic a branch of, realizes more high-power Laser output.It is based on such principle, and is thoroughly high to the light of a kind of polarization direction (p attitude), high anti-to the light of another kind of polarization direction (s attitude).The synthetic mirror of light beam is to can according to different coupled light beam wavelength, designing the synthetic eyeglass (perhaps light beam synthetic prisms) of light beam of different incidence angles degree.In the design process the synthetic mirror of light beam and a slice total reflective mirror are placed in the fixing tool at a certain angle, make the light beam conversion portion compacter, system is miniaturization more.
The output coupled lens of the technical program adopts positive and negative lens combination to realize high-quality Laser output, in remote little spot size and the high power density of keeping.
The technical program has following technique effect:
Output in the wide temperature range: the inconsistent or crystal by the crystal-cut direction is debugged the inconsistent of orientation, and it is different that the light beam powers that two cover laser cavities are exported vary with temperature characteristic, and namely corresponding different temperature range exists the part juxtaposition; By temperature feedback and circuit control, the work that any light beam can't be realized can be finished jointly by two-beam.
High-power output more in the wide temperature range: solve common module lower can't the normal operation of hot conditions (more than 50 degree), perhaps single laser beam cannot be realized the more difficult problem of high-power output, adopt the synthetic mirror of light beam that two bundle laser are synthetic a branch of, realize more high-power output, can regulate respectively two bundle laser simultaneously, realize the interior Laser output of wide region.
Improve light beam output noise frequency: two bundle laser beams are synthetic a branch of, improved to a great extent the output noise frequency, when module is used on the particular instrument, because less than the resolution capability of human eye, can solving thus to a certain extent, the length that luminous point is passed by in the frequency interval is difficult at present the broken string problem of capturing.
Volume is little: owing to not having large heat abstractor and circuit control, the module design can be satisfied existing market to laser miniaturization demand.We utilize this scheme at present, can accomplish the laser module of bore≤10mm, length≤50mm
Wide temperature laser module of the present invention has been realized small size, wide temperature, more high-power laser module, the design frock is compact, is convenient to mobile carrying, and can be widely used in some for the stricter application of volume requirement, as: military affairs, measure and wait the industry that needs wider range.
