Description
Technical field the present invention relates to laser and optical field, relates in particular to a kind of optical texture and application thereof.
When common ruddiness of patent background and blue combiner, need to make of two Different L D pedestals, institute takes up space big, is unfavorable for the laser miniaturization; To the light of identical wavelength, in order to strengthen light intensity, also need to carry out polarization with two LD and close bundle in addition, the laser volume is just very big like this; The patent No. is that the United States Patent (USP) of US005909310A and US006310989B1 proposes, in fiber optic communication field, after the luminous point of two optical fiber utilized same collimated, utilize the polarization beam cementing prism that it is collimated into the light beam that is parallel to each other again, but its only propose to use fiber optic communication field.Simultaneously in application number is " a kind of semiconductor pump laser of wide temperature range " patent application of 200620070891.9, the problem that the wide temperature structure of dual wavelength pumping laser also exists pumping simultaneously not share the same light.
Summary of the invention the object of the invention provides and a kind ofly is provided with a plurality of LD, but little optical texture of volume and the application in laser thereof.
For realizing above purpose, optical texture of the present invention constitutes multicore sheet LD by a plurality of fixed L D chip secured in parallel adjacent more than two or two on same heat sink seat.
Above-mentioned multicore sheet LD by two LD chip secured in parallel in same heat sink when seat, 1/2 wave plate is installed in light outgoing place of a LD chip therein, the polarised light angle at 45 of its optical axis direction and this LD chip emergent light, the light of light of She Chuing and the ejaculation of another chip is collimated into the orthogonal directional light in polarization direction that two bundles intersect by collimating lens like this, by the birefringence beam cementing prism that is arranged on the two-beam infall, two-beam is combined into a branch of light or two identical or close bundle directional lights of direction again.
When the polarization direction of two above-mentioned LD chip emergent lights is vertical mutually, do not adopt 1/2 wave plate.
Above-mentioned multicore sheet LD is focused it on the same point of laser microplate by condenser lens after being combined into two identical or close bundle directional lights of a branch of light or direction again, and pumping produces laser.
Above-mentioned birefringence beam cementing prism comprises the different birefringece crystal prisms of two same material optical axis directions or the birefringece crystal angle of wedge and the uniform optical medium angle of wedge.
When above-mentioned multicore sheet LD comprises more than two or two adjacent a plurality of fixed L D chip, be the directional light that multi beam intersects, multi-beam adjusted parallel by optical prism again by the collimating lens collimation.
The present invention adopts said structure, and the light beam that can be used for light beams of different wavelengths or identical wavelength closes bundle, also can be used for the polychrome combiner; Multicore sheet LD can be used for making more powerful ruddiness LD, blue light LD and red blue light LD assembly, is used to make the micro-slice laser of high-power micro-slice laser or two different pumping wavelengths, also can be used for making high-power wide temperature semiconductor pump laser.

Embodiment sees also shown in Fig. 1-4, the present invention is by a plurality of LD chips 101,102,103 adjacent more than two or two ... secured in parallel constitutes multicore sheet LD1 on same heat sink seat 11, a plurality of LD chips 101,102,103 ... wavelength can be identical, also can be different.The concrete application of this optical texture is as follows:
As shown in Figure 1, multicore sheet LD1 is by two LD chips 101,102 parallel being encapsulated in when constituting on the same heat sink seat 11,1/2 wave plate 21 is installed in light outgoing place of a LD chip 102 therein, the polarised light angle at 45 of its optical axis direction and LD chip 102 emergent lights, the light of She Chuing is vertical mutually with another chip 101 ejaculation polarisation of light directions like this, after two-beam is collimated by collimating lens 3, form the orthogonal directional light in polarization direction that two bundles intersect, certain angle is arranged between the two, its hot spot very large tracts of land overlaps, birefringence beam cementing prism 4 is arranged on the two-beam infall, and two-beam is combined into a branch of light or two identical or close bundle directional lights of direction.Birefringence beam cementing prism 4 is made of the different birefringece crystal prisms of two same material optical axis directions or the birefringece crystal angle of wedge and the uniform optical medium angle of wedge.When the polarization direction of two LD chip 101,102 emergent lights is vertical mutually, do not need to adopt 1/2 wave plate.
For example, two chips, 101,102 wavelength of twin-core sheet LD 1 identical can be made than twice ruddiness LD of common single-chip LD power and blue light LD.Twin-core sheet 101,102 can be respectively ruddiness LD chip and blue light LD chip, makes the red blue light LD assembly of small size.In addition, the light that this optical texture collimation of process closes behind the bundle can be used as pump light, makes the micro-slice laser of high-power micro-slice laser or two different pumping wavelengths.
