Abstract
The utility model relates to the field of lasers, in particular to the field of Q-switches. An electro-optical Q-switch of the utility model respectively combines an electro-optical crystal whose twoends are Brewster's angles with two window sheets whose one ends are the Brewster's angles, and is arranged in a ceramic outer shell. The parallel end surfaces of the window sheets are glued with a glass flat plate, thereby realizing the sealing of the whole structure. When a light beam shoots into from one end, since the window sheets are in a wedged shape with the Brewster's angle, laser can basically and straightly pass through a Q-crystal, can eliminate the inner cavity consumption which the electro-optical Q-switch is used on a Q-switch, and simultaneously protects the crystal from deliquate and the like.
Description
Technical field
The utility model relates to laser field, relates in particular to the Q switching field.
Background technology
Electric-optically Q-switched switch adopts KDP or KD*P crystal to make usually, because the easy deliquescence of this crystalloid, usually need crystal is sealed in the box, and in box, add index-matching fluid, because there is certain volatilization in index-matching fluid, need to add matching fluid after using a period of time, this brings convenience scarcely to practical application.As the method for direct employing sealing air, then again owing to there is not anti-reflection certain cavity loss that brings at crystal end-face.
The utility model content
At the problems referred to above, the structure that the utility model proposes a kind of electro-optical Q-switch solves, and the technical solution of the utility model is:
A kind of electro-optical Q-switch, comprise that ceramic package outside the parcel electrooptic crystal and the gold-plated electrode that is connected on the electrooptic crystal approach ring or gold-plated electrode thin slice, thin ring of described gold-plated electrode or gold-plated electrode thin slice and weldering are tied in electrode, and described electrooptic crystal being carried out q-operation by the voltage regulator circuit that is connected on the electrode, described electrooptic crystal two logical light end faces are Brewster's angle inclined-planes; Described electrode also comprises porcelain bushing, and its two ends perforate is used to place electrode; Center, described ceramic package side is opened an aperture and is injected colloid, and electrooptic crystal and ceramic package are bonded as one; Described electrooptic crystal two logical light faces also are provided with diaphragm, a logical light face of described diaphragm is the plane, the logical light face of another one is the Brewster's angle inclined-plane, and the Brewster's angle inclined-plane of diaphragm is parallel with electrooptic crystal Brewster's angle inclined-plane or approaching parallel placement.
Further, the logical light face on the plane of described diaphragm is the optical cement glass planar sheets also, and described glass planar sheets also is bonded in described ceramic package by glue-line, forms the hermetically-sealed construction of one.
The utility model adopts this technical scheme, have to make laser substantially linearly by adjusting Q crystal, but the cancellation electrooptic crystal is used for the cavity loss that Q switching brings, and protects crystal not to be subjected to the technical advantage of deliquescence simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Now with embodiment the utility model is further specified in conjunction with the accompanying drawings.
Consult shown in Figure 1, electro-optical Q-switch of the present utility model, comprise that ceramic package 107 outside the parcel electrooptic crystal 101 and the gold-plated electrode that is connected on the electrooptic crystal 101 approach ring or gold-plated electrode thin slice 103, thin ring of described gold-plated electrode or gold-plated electrode thin slice 103 and scolding tin weldering are tied in electrode 106, and by the voltage regulator circuit that is connected on the electrode 105 described electrooptic crystal 101 are carried out q-operation.Further, 101 liang of logical light end faces of described electrooptic crystal are Brewster's angle inclined-planes; Described electrode 105 also comprises porcelain bushing 106, and its two ends perforate is used to place electrode 105; Center, described ceramic package 107 side is opened an aperture 104 and is injected colloid, electrooptic crystal 101 and ceramic package 107 are bonded as one, electrooptic crystal 101 closely are connected with ceramic package 107, thereby fix electrooptic crystal 101, simultaneously, aperture 104 also is as the exhaust air-filled pore; 101 liang of logical light faces of described electrooptic crystal also are provided with diaphragm 102A, the logical light face of described diaphragm 102A is the plane, the logical light face of another one is the Brewster's angle inclined-plane, and the Brewster's angle inclined-plane of diaphragm 102A is parallel with electrooptic crystal 101 Brewster's angle inclined-planes or approaching parallel placement.Owing to adopt ceramic package 107, can directly put into solder, high-temperature baking melts connection electrode 105, and ceramic package 107 can be suppressed with mould in batches by die sinking.
Further, the logical light face on the plane of described diaphragm 102A is optical cement glass planar sheets 102B also, and described glass planar sheets 102B also is bonded in described ceramic package 107 by glue-line 108, forms the hermetically-sealed construction of one.
Light beam is during from an end incident, because diaphragm 102A is the wedge shape of Brewster's angle, can make laser substantially linearly by transferring the electrooptic crystal 101 of Q, but cancellation electrooptic crystal 101 is used for the cavity loss that Q switching brings, and protects crystal not to be subjected to deliquescence simultaneously.
The utility model adopts longitudinal electro-optic effect to realize q-operation.Press and pressuring method realizes that it transfers the Q function the i.e. polarization direction half-twist that adds high pressure and make incident beam at electrooptic crystal 101 two ends, Q switching processing closed condition by moving back of voltage regulator circuit; Return the high pressure on the electrooptic crystal 101 when transferring Q, then the polarization direction of incident ray polarisation is constant, thereby forms laser generation.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; but the those skilled in the art should be understood that; in the spirit and scope of the present utility model that do not break away from appended claims and limited; can make various variations to the utility model in the form and details, be protection range of the present utility model.
