Abstract
The utility model relates to a high power fiber laser collimating mirror using aspherical lens. The high power fiber laser collimating mirror uses the aspherical lens, and is high in beam quality and low in spherical aberration loss. The high power fiber laser collimating mirror comprises a water cooling circulation groove (2), an aspherical collimating lens (3), a protective lens (4), a collimating unit connection port (5), a calibration screw (7) and a collimating incident clamping head (10), wherein the collimating incident clamping head (10) is arranged above the lens cone and is connected with the water cooling circulation groove (2) through a screw thread, the protective lens (4) is arranged in the lens cone, the collimating unit connection port (5) is fixed at the bottom of the lens cone by a wire ring, and the aspherical collimating lens (3) is fixed on the inner wall of the lens cone by the calibration screw (7). The high power fiber laser collimating mirror not only overcomes the chromatism caused by the aspherical mirror, but also improves the beam quality influenced by the spherical aberration.
Description
Technical field:
The utility model relates to a kind of high-power fiber collimating mirror that adopts aspherical lens.
Background technology:
At present, known import and domestic collimating mirror all adopt the planoconvex lens of two (multi-disc) lens set or monolithic as the collimating optics unit, and all there is the deficiency of self in these two kinds of designs.When using two or multi-disc lens set as the optical alignment unit, all can the reflecting part light beam by every eyeglass, cause entire light to have repeatedly the area loss of crossing, thereby reduced the energy of light beam; Use the planoconvex lens of monolithic as the optical alignment unit, can be because sphere differ, after the diverging light that causes electric light source to penetrate was collimated directional light, beam quality was not good, and collimated light is dispersed larger, is unfavorable for using.
The utility model content:
The utility model is exactly for the problems referred to above, and the high-capacity optical fiber laser collimating mirror of the employing aspherical lens that a kind of beam quality is high, the spherical aberration loss is little is provided.
In order to realize above-mentioned purpose of the present utility model, the utility model adopts following technical scheme,
Comprise water cooling circulation groove, non-sphere collimation mirror sheet, protection eyeglass, collimate unit connector, calibration screw, collimate the incident chuck; collimation incident chuck is arranged at the top of lens barrel and is connected with the water cooling circulation groove by screw thread; the protection eyeglass is arranged in lens barrel; the collimation unit interface is fixed in the bottom of lens barrel by wire ring, the non-sphere collimation mirror sheet is fixed on the lens barrel inwall by the calibration screw.
The top of described water cooling circulation groove is provided with the water-cooled interface.
Described water cooling circulation groove is fixed on the outside of lens barrel.The calibration screw can be adjusted the position of aspherical lens, makes the luminous energy of dispersing of the specific wavelength that penetrates from pointolite be calibrated to the most to greatest extent directional light, in order to focus on.
The beneficial effects of the utility model:
The utility model has promoted the beam quality that has influence on due to spherical aberration when having overcome the aberration that aspheric mirror brings., on the one hand having overcome the beam quality that spherical aberration causes poor, dispersion angle is large; The energy attenuation that has overcome on the other hand that light beam is crossed face often and caused by Multi reflection.
Description of drawings:

In Fig. 1,1. incidence point light source, 2. water cooling circulation groove, 3. non-sphere collimation mirror sheet; 4. the protection eyeglass, 5. collimate the unit connector, 6. the parallel beam after collimation lens, 7. collimation lens calibration screw; 8. incident divergent beams, 9. water-cooled interface, 10. collimation incident chuck.
Fig. 2 is schematic diagram of the present utility model.
In Fig. 2,3, the non-sphere collimation mirror sheet, 11, the parallel incident light of different wave length, the focus point of 12,532 nano wave length light, the focus point of 13,680 nano wave length light, the focus point of 14,1064 nano wave length laser.
Embodiment:
Comprise water cooling circulation groove 2, non-sphere collimation mirror sheet 3, protection eyeglass 4, collimate unit connector 5, calibration screw 7, collimate incident chuck 10; collimation incident chuck 10 is arranged at the top of lens barrel and is connected with water cooling circulation groove 2 by screw thread; protection eyeglass 4 is arranged in lens barrel; collimation unit interface 5 is fixed in the bottom of lens barrel by wire ring, non-sphere collimation mirror sheet 3 is fixed on the lens barrel inwall by calibration screw 7.
The top of described water cooling circulation groove 2 is provided with water-cooled interface 9.
Described water cooling circulation groove 2 is fixed on the outside of lens barrel.
In Fig. 2, choose general wavelength 1064 nanometers of fiber laser, 60 millimeters of collimating mirror focal lengths are example, use 532 nano wave length green glows and 680 nano wave length ruddiness to record real focal length and be respectively F ruddiness and F green glow, calculate by formula, the center thickness of substitution non-sphere collimation mirror sheet and the index meter of material are calculated the focal length F of 1064 nano wave length laser again.By the calibration screw 7 in Fig. 1, eyeglass is placed on suitable position again, makes the laser of 1064 nano wave lengths that incidence point light source 1 penetrates from Fig. 1 can be calibrated to greatest extent the directional light ejaculation.Thereby overcome the focus error that aberration that aspheric mirror brings causes, also because used aspherical lens, brought the spherical aberration limit more excellent than complex optics, thereby promoted the entire light quality, got the minimum collimated light beam angle of divergence.
