Described first order OPO is an II class phase matched, and outside short wavelength's pump light 12 is input to first resonant cavity with the described first order OPO of pumping.Described first order OPO produces flashlight and ideler frequency light, and described flashlight and ideler frequency light two bundle parameteric light wavelength equate or be close that the polarization direction is vertical, is called degeneracy or nearly degeneracy laser 13; When this degeneracy or nearly degeneracy laser 13 pass through polarization spectro element 1, be divided into two bundles, a branch of polarised light does not change the direction of propagation, advances along a limit of triangular ring cavity, and a branch of in addition polarised light changes direction, advances along an other limit of triangular ring cavity.90 degree polarization rotators 2 are the engagement point of two-beam in annular chamber, every Shu Jiguang is after passing 90 degree polarization rotators 2, the direction that change of polarized direction becomes and other beam of laser is original is the same, to advance in the other direction along the light path that other beam of laser had before been passed through simultaneously, so two kinds of polarised lights is the same through the path, all pass through polarization spectro element 1 at last again and return first order OPO, participate in the optical parameter effect, polarised light has so far been finished a polarization circulation.Such structure has formed a single polarised light in annular chamber, second level OPO is equivalent to two end faces by the while pumping in annular chamber, produces long wavelength laser 14, and long wavelength laser 14 is exported by wherein eyeglass of triangular ring cavity the most at last.90 degree polarization rotators 2 be placed on long wavelength laser 14 in the annular chamber without light path on, to reduce loss.When 7 pairs of degeneracys of first order OPO chamber mirror or nearly degeneracy laser 13 high when saturating, degeneracy or nearly degeneracy laser 13 is big resonance of inner formation in whole polarised light cyclic resonance chamber, be equivalent to first order OPO and second level OPO and formed an inner-cavity structure, second level OPO is in the chamber of first order OPO; When 7 pairs of degeneracy laser part inverse time of first order OPO chamber mirror, degeneracy or nearly degeneracy laser 13 also move in polarised light cyclic resonance chamber at the resonant cavity interior resonance of first order OPO, are equivalent to first order OPO and second level OPO and have formed a Compound Cavity structure.Generally speaking, first order OPO chamber mirror 7 is preferably degeneracy or nearly degeneracy laser 13 high saturating.7 pairs of short wavelength's pump lights of first order OPO chamber mirror 12 are high anti-and high saturating, two kinds of pump modes of corresponding round trip pumping and one way pumping.The high-reflecting film of the first chamber mirror, 3 plating degeneracys or nearly degeneracy laser 13.The long wavelength laser that second level OPO produces is exported from annular chamber, and the annular chamber chamber mirror that plays output action is high saturating to the long wavelength laser 14 that second level OPO produces, as first speculum 4 among Fig. 1.
Second embodiment of cascade OPO of the present invention, as shown in Figure 2, the left chamber mirror 6 of second level OPO is put into outside the annular chamber, near second speculum 5, on the extended line of light path outside the chamber between first speculum 4 and second speculum 5; Right chamber mirror 10 also is put into outside the annular chamber, and near first speculum 4, on the extended line of light path outside the chamber between first speculum 4 and second speculum 5, the high transmittance film of first speculum 4 and second speculum, 5 plating long wavelength lasers 14 is to reduce loss.
The 3rd embodiment of cascade OPO of the present invention, as shown in Figure 3.A left side chamber mirror 6 and right chamber mirror 10 also can select wherein one to be placed on outside the annular chamber, have selected right chamber mirror 10 to be placed on outside the annular chamber among the figure, on the extended line of light path outside the chamber between the polarization spectro element 1 and first speculum 4.Second level OPO can be placed in any a section of annular chamber, in embodiment 1 and embodiment 2, be placed on the light path between first speculum 4 and second speculum 5, in embodiment 3, then be placed on the light path between the polarization spectro element 1 and first speculum 4.
The annular chamber part can comprise a plurality of speculums, and its shape is triangle not necessarily, also can be various polygons such as parallelogram.But the chamber mirror of forming annular chamber is many more, and then loss is big more.The 4th embodiment of cascade OPO, as shown in Figure 4, annular chamber is a parallelogram, has increased by the 3rd speculum 11.In the annular chamber light path, also can use prism to replace speculum, finish the function of folded optical path.
The element of polarization spectro described in the literary composition 1 can be a polarizer, also can be Glan prism etc. other can finish the polarizer of polarized light beam splitting.Can put into not the optical element of polarisation-affecting in the light path regulates as light path.90 degree polarization rotators 2 can be 1/2 wavelength wave plates of degeneracy or nearly degeneracy laser 13, and its optical axis becomes miter angle with two polarization directions of degeneracy or nearly degeneracy laser 13.90 degree polarization rotators 2 also can be other polarization rotation elements.
The most typical application of the present invention be in cascaded infrared OPO, pump light is the laser of 1064nm, first order OPO is adopted as the nonlinear crystal of KTP class as nonlinear crystal, produce near degeneracy of 2128nm or nearly degeneracy laser, this degeneracy or nearly degeneracy laser pumping second level OPO, second level OPO adopts ZGP as nonlinear crystal, form efficiently 3～5 microns in infrared output.If adopt structure shown in Figure 1, then short wavelength's pump light 12 is the laser of 1064nm, first nonlinear crystal 8 is a ktp crystal, second nonlinear crystal 9 is the ZGP crystal, the wavelength of degeneracy or nearly degeneracy laser 13 is about 2128nm, in order to obtain near degeneracy or the nearly degeneracy laser the 2128nm, ktp crystal will satisfy degeneracy or nearly degenerate condition.In order to obtain greater efficiency, ktp crystal will adopt II class phase matched simultaneously.Wavelength and output light wavelength according to short wavelength's pump light 12, under the working temperature of 300K, two formula according to the foregoing conservation of momentum and the conservation of energy, and the refractive index expression formula of crystal itself, can calculate the angle of degeneracy light requirement, in ktp crystal main shaft xyz coordinate system, incident light is about degeneracy or 13 outputs of nearly degeneracy laser that 54 degree can obtain 2128nm with z axle clamp angle in the xz plane.For the ease of using, normally, make that short wavelength's pump light 12 of 1064nm can the normal incidence plane of crystal the plane cutting of crystal along vertical this direction.For different crystal, its degeneracy II class phase matched angle is different, but those skilled in the art can obtain angle value with aforesaid step according to known general knowledge and prior art.
The present invention is simple in structure, has made full use of the degeneracy or the nearly degeneracy laser of first order OPO output, does not have attachment devices such as long wave ankylose light, is a cascade OPO efficiently.
