Abstract
The utility model provides a two-dimensional Q switch rotary adjusting bracket comprising a Q switch; and a first plate is fixedly arranged at one side of the Q switch, a shaft is arranged on the first plate, a hole is arranged in a second plate, the shaft of the first plate is inserted into the hole of the second plate to form rotatable clearance fit, the first plate and the second plate are locked mutually by a fastening screw; one side of the second plate, contacted with an optical platform, is provided with a locating pin; a hole is arranged at a position on the optical platform, corresponding to the locating pin; and the locating pin 4 on the second plate is inserted into the hole in the optical platform to form rotatable clearance fit. The two-dimensional Q switch rotary adjusting bracket has the beneficial effects that as the Q switch has two rotating freedoms, by utilizing the two-dimensional Q switch rotary adjusting bracket, the precision for stationery fitting is improved, so as to carry out longitudinal and transverse precise adjustment conveniently, improve the angle adjusting range of the Q switch and reduce the operating difficulty.
Description
Technical field
The utility model relates to a kind of Q switching fixture, particularly a kind of two-dimentional Q switching rotation adjusting bracket.
Background technology
Q switching is important optical element in the laser optical system, it by blocking-up and not the reflection channel of blocking light suppress and produce laser pulse.When not applying radiofrequency signal to PZT (piezoelectric transducer), quartz crystal keeps its original conventional refractive index, sees through between the directional light that is emitted by laser bar that quartz crystal is anxious to stop, and passes quartz crystal, return laser light rod again through the rear reflector emission.
In case apply radiofrequency signal to PZT (piezoelectric transducer), PZT (piezoelectric transducer) produces ultrasonic wave immediately in the quartz crystal body.Ultrasonic wave compressing quartz crystal changes its refractive index, and the light that sees through quartz crystal refraction takes place and departs from rear reflector, and making does not have light return laser light rod.Because light return laser light rod is the necessary condition of excitation laser, so lasing process stops, therefore apply and cancel radiofrequency signal to PZT (piezoelectric transducer), be the important control means of turning off and discharge laser.
The adjustment of the angle of Q switching is a very important step in the laser debug process.Usually Q switching is to be directly installed on the optical table, and perhaps Q switching is fixed on and is installed to optical table on the base again, as shown in Figure 1.Q switching uses long slot bore to fix, and when needing to adjust, loosening hold-down screw is manually adjusted.Though this kind mode can reach the effect of adjustment to a certain extent, has some shortcomings: 1,, can't carry out Precision trimming owing to, regulate difficulty without any location measure.2, the angle of Q switching need be carried out two dimension adjustment, and this kind structure can only be regulated a rotational freedom, and adjustment can only realize by emergency modes such as cushioning aluminium foils as the need two dimension.
Summary of the invention
At structural deficiency in the prior art, the purpose of this utility model provides a kind of two-dimentional Q switching rotation adjusting bracket, makes Q switching can simply carry out the angular adjustment of two dimensions, and quick adjustment is precisely located.
For achieving the above object, the technical solution adopted in the utility model provides a kind of two-dimentional Q switching rotation adjusting bracket, wherein: this adjusting bracket includes Q switching, one side of Q switching is fixed with first plate, an axle is arranged on first plate, a hole is arranged on second plate, form rotary matched in clearance in the hole of axle insertion second plate of first plate, first plate and second plate are locked mutually by trip bolt; Second plate contacts a side and is provided with an alignment pin with optical table, be provided with a hole with the alignment pin correspondence position on the optical table, forms rotary matched in clearance in the hole that the alignment pin 4 on second plate inserts on the optical table.
Effect of the present invention is because Q switching has two rotational freedoms, use this two dimension Q switching rotation adjusting bracket, improved the precision of secure fit, carry out vertical, horizontal fine adjustment easily, improve the angle of regulation range of Q switching, and reduced operation easier.

Embodiment
In conjunction with the accompanying drawings two-dimentional Q switching rotation adjusting bracket structure of the present utility model is illustrated.
As shown in Figure 1, 2, 3, two-dimentional Q switching rotation adjusting bracket of the present utility model, this adjusting bracket includes Q switching 1, one side of Q switching 1 is fixed with first plate 2, an axle is arranged on first plate 2, a hole is arranged on second plate 3, form rotary matched in clearance in the hole of axle insertion second plate 3 of first plate 2, first plate 2 and second plate 3 are locked mutually by trip bolt 7; Second plate 3 contacts a side and is provided with an alignment pin 4 with optical table 6, be provided with a hole with alignment pin 4 correspondence positions on the optical table 6, forms rotary matched in clearance in the hole that the alignment pin 4 on second plate 3 inserts on the optical table 6.
Also can fix between described second plate 3 and the optical table by screw lock.
Implementation procedure of the present utility model is, Q switching is fixed on first plate 2 by two hexagon socket countersunk flat cap head screws, when regulating Q switching 1 angle, at first loosening holding screw 7, be rotary matched in clearance this moment between first plate 2 and second plate 3, rotates first plate 2 and can realize Q switching angular adjustment longitudinally.After reaching best angle, the locking effect that reaches is no longer rotated in fixation between locking holding screw 7, the first plates 2 and second plate 3.When needing the adjusting lateral angles, the hold-down screw (figure do not show) of at first loosening second plate 3 between optical table 6 can also be the matched in clearance of rotating between alignment pin 4 and the optical table 6, rotates Q switching 1 and can realize with alignment pin 4 being the horizontal corner adjusting of axle.
