Technical field
The present invention relates to laser field, relate in particular to the disengagement chamber field of lasers of debugging more complicated.
Background technology
Conventional laser chamber disengagement chamber is fixed on the laser cavity sheet on the accurate adjustment rack usually; Through regulate two dimension, three-dimensional trim holder make laser before and after the chamber sheet parallel to each other; Reached the effect of laser starting of oscillation, but, regulated to use also can produce deformation for a long time because the adjustment rack volume is big; And the price of the adjustment rack of degree of precision is very high, and this method is used very inconvenient concerning the laser of some small size, compactedness.
Summary of the invention
To above-mentioned shortcoming, the object of the invention is to design a kind of control method and adjusting device of laser cavity simply and easily.
For achieving the above object; The technical scheme that the present invention proposes is: a kind of control method of laser cavity; It is characterized in that the rotation angle of wedge that in laser cavity, inserts a pair of rotatable adjusting is tentatively regulated the optical element in the laser cavity 104A, 104B then; Regulate the optical parallel degree of whole resonant cavity through the adjustment of its relative rotation angle and the whole anglec of rotation, to reach the purpose of laser resonance output.
During concrete the use, the inventive method can be passed through following steps: at first through collimated light beam to the debugging that collimates of each laser component of Effect of Back-Cavity Mirror 101,102, laser crystal 103 before comprising; Collimation debugging is accomplished the back and the adjustment of the relative rotation of 104A, 104B and the whole anglec of rotation is regulated the optical parallel degree of whole resonant cavity through rotating the angle of wedge.
In addition; This laser cavity can also adopt following method; Realization directly earlier fixes preceding Effect of Back-Cavity Mirror 101,102 adjusting of laser cavity at compact machine center, the drift angle before tentatively recording through collimated light then between the chamber sheet of Effect of Back-Cavity Mirror; Tentatively rotate this according to this drift angle rotation angle of wedge sheet is arrived the corresponding rotation angle; Whole again rotation this to the rotation angle of wedge to 104A, 104B, tentatively parallel to laser cavity, more repeatedly thin tuning angle of wedge relative position and the unitary rotation angle of wedge to reach required parallel chamber.
Further; The rotation angle of wedge is realized rotation relatively and whole rotation to 104A, 104B through adjusting device, and adjusting device comprises: the rotational fixation platform of a cylinder type, and one of them angle of wedge sheet 104B is fixed on the second cylindrical shape assembling jig 204 through the mode of gluing or mechanical fixation; Another angle of wedge sheet 104A is fixed on the first cylindrical shape assembling jig 203 through the mode of gluing or mechanical fixation; The second cylindrical shape assembling jig 204 is nested in the first cylindrical shape assembling jig 203, forms an integral body, and integral body is nested on the stationary fixture 205 again; Can be rotated adjusting between each anchor clamps, regulate the back and fix with screw 201,202.
Description of drawings
Fig. 1 carries out the laser structure that laser cavity is regulated for adopting the present invention;
The rotation angle of wedge right adjusting device profile of Fig. 2 for being mentioned among the present invention;
Fig. 3 rotates the right adjusting device overall structure figure of the angle of wedge for the present invention.
Embodiment
Combine accompanying drawing and embodiment that the present invention is further specified at present.
101. laser ante-chamber, 102. laser back cavities, 103. gain mediums, 104A and 104B. angle of wedge sheet, 201 and 202. hold-down screws, 203. first cylindrical shape assembling jigs, 204. second cylindrical shape assembling jigs, 205. stationary fixtures.
Among Fig. 1; 101,102 is chamber sheet before and after the laser, and 103 is gain medium; 104A; 104B is a vertical angles angle of wedge sheet, and the optical parallel degree of whole resonant cavity is regulated in the relative rotation angle through angle of wedge sheet 104A and 104B and the adjustment of the whole anglec of rotation, can reach the purpose of laser resonance output.Concrete when using this adjusting device, can be in advance through collimated light beam to comprising preceding Effect of Back-Cavity Mirror, laser crystal can be regulated through the right adjusting of the angle of wedge of the present invention after the basic debugging completion in each interior laser component debugging that collimates again.The rotation angle of wedge can be the same or different to 104A, 104B material, and the rotation angle of wedge can be the same or different to 104A, 104B angle.
In addition, Fig. 1 is a kind of typical laser structure of this laser cavity adjusting device, but is not unique applicable cavity configuration; Various laser cavity structures commonly used such as flat-concave cavity, concavo-concave chamber all are applicable to this control method, and in the laser cavity except gain medium 103, regulate with the rotation angle of wedge outside 104A, the 104B; Can also comprise nonlinear crystal; Adjusting Q crystal, polarizing prism, laser cavity element commonly used such as Amici prism.
Like Fig. 2, shown in Figure 3, Fig. 2 is fixed on two and has and have vertical angles one angle of wedge angle regulator, wherein a 104A on the scale cylinder for a pair of; 104B is a pair of angle of wedge sheet; The first cylindrical shape assembling jig 203 is the assembling jig of angle of wedge sheet 104A, and the second cylindrical shape assembling jig 204 is the assembling jig of angle of wedge sheet 104B, and stationary fixture 205 is the right assembling jig of the whole angle of wedge; Hold-down screw 202; Be used for fixing relative rotation angle between angle of wedge sheet 104B and the angle of wedge sheet 104A, hold-down screw 201 is used for fixing the right anglec of rotation of the whole angle of wedge.When the needs rotation adjusting, regulate the optical parallel degree of whole resonant cavity through the adjustment of the relative rotation angle between adjusting angle of wedge sheet 104A and 104B and the whole anglec of rotation.
This patent also can directly earlier fix preceding Effect of Back-Cavity Mirror 101,102 at compact machine center; Tentatively record the drift angle between the sheet of chamber through collimated light then; Tentatively rotate this according to this drift angle rotation angle of wedge sheet is arrived the corresponding rotation angle; Whole again rotation this to the rotation angle of wedge to 104A, 104B, tentatively parallel to laser cavity, more repeatedly thin tuning angle of wedge relative position and the unitary rotation angle of wedge to reach required parallel chamber.
Because the angle of wedge is insensitive to mechanical deformation, whole laser has more high stability, and this patent can add this patent angle of wedge in multi-cavity chip laser system right, as if after the little imbalance of light path, can also finely tune the angle of wedge to the calibration of laser chamber to the optimum position.
Although specifically show and introduced the present invention in conjunction with preferred embodiment; But the those skilled in the art should be understood that; In the spirit and scope of the present invention that do not break away from appended claims and limited; Can make various variations to the present invention in form with on the details, be protection scope of the present invention.
