Abstract
The present invention provides a kind of dual wavelength polarization beam combiner, its wollaston prism and dual wavelength wave plate for being set along optical path direction, utilize the light-dividing principle and light path principle of wollaston prism, wollaston prism transmits the two orthogonal polarised lights of beam polarization state to dual wavelength wave plate, because dual wavelength wave plate has the out of phase lag characteristic of different wave length, therefore can be so that output polarization state is identical and has the combined beam light of different wave length, it is seen that the dual wavelength polarization beam combiner of this case is ingenious in design and simple in construction.
Description
Technical field
The present invention relates to optics field, more particularly to a kind of dual wavelength polarization beam combiner.
Background technology
It is existing, it is necessary to treat the linearly polarized light of detectable substance output specific wavelength in the detection machine of some Application Optics
Equipment general structure it is complex, it is necessary to which multiple couplers or the polarizer etc. combine, cost is higher.
The content of the invention
It is an object of the invention to provide a kind of simple in construction and realize the dual wavelength polarization coupling of different wave length polarization coupling
Device.
In order to realize the purpose of the present invention, the present invention provides a kind of dual wavelength polarization beam combiner, is set along optical path direction
Wollaston prism and dual wavelength wave plate.
Further scheme is that dual wavelength wave plate is arranged on the output end face of wollaston prism.
Further scheme is that wollaston prism is used for the two beam input lights for receiving different wave length.
Further scheme is, the wavelength of the phase delay of dual wavelength wave plate and input light it is Wavelength matched.
The invention has the advantages that utilize the light-dividing principle and light path principle of wollaston prism, Wollaston
The orthogonal polarised light of beam polarization state of prism transfer two is to dual wavelength wave plate, because dual wavelength wave plate has different wave length not
Same-phase lag characteristic, therefore can be so that output polarization state is identical and has the combined beam light of different wave length, it is seen that the dual wavelength of this case is inclined
The bundling device that shakes is ingenious in design and simple in construction.
Brief description of the drawings
Fig. 1 is the index path of dual wavelength polarization beam combiner embodiment of the present invention.
Below in conjunction with drawings and Examples, the invention will be further described.
Embodiment
Reference picture 1, the wollaston prism 12 and dual wavelength wave plate 11 that dual wavelength polarization beam combiner is set along optical path direction,
Wollaston prism 12 is made by birefringece crystal Yttrium Orthovanadate (YVO4) monocrystalline, and it is typically used as splitting light into two mutually
The light of vertical polarization state, and this case is used as closing light according to light path principle.Dual wavelength wave plate 11 has with different wave length
There are different phase delay, such as light for 635nm wavelength, wave plate 11 is relative to full-wave plate, for the light of 532nm wavelength, ripple
Piece 11 is relative to half-wave plate.Dual wavelength wave plate 11 can be snugly arranged on the output end face of wollaston prism 12, exported
The opposite side of end face is then the input end face of wollaston prism 12.
When closing beam output, selection is incident to wollaston prism 12 with the Wavelength matched two-beam of dual wavelength wave plate 11, can
It is the light of random polarization state with input, also can be the vertical light of polarization state, under the effect of the closing light of wollaston prism 12,635nm
The polarization combiner of the horizontal state of polarization of the polarised light of the polarization and vertical polarization of the light of wavelength and the light of 532nm wavelength and in output end
Face exports.
Because the optical axis of dual wavelength wave plate is set with vertical direction in 45 ° of at an angles, so the polarised light phase of 635nm wavelength
For not rotated by full-wave plate, its polarization state, the polarised light of 635nm wavelength is with respect to half-wave plate, the rotation of its polarization state
90 °, the polarization state of final two-beam exports from wave plate in the same manner.
Therefore utilize the light-dividing principle and light path principle of wollaston prism, wollaston prism transmission two
The orthogonal polarised light of beam polarization state is to dual wavelength wave plate, because the out of phase that dual wavelength wave plate has different wave length postpones
Characteristic, therefore can be so that output polarization state is identical and has the combined beam light of different wave length, it is seen that the dual wavelength polarization beam combiner of this case is set
Count ingenious and simple in construction.
