Abstract
The utility model discloses a kind of electric-optically Q-switched DKDP constructions of switch of microstress, gold electrode of the chromium as substrate is plated on DKDP crystal, then the conductive adhesive tape for using head and the tail not to be in contact carries out contact chromium as the gold electrode of substrate, conductive adhesive tape is placed into switch insulation shell, it is in contact above with gold-plated electrode contact pin and the transmitting of electric signal is effectively guaranteed, jack structure is devised on gold-plated electrode contact pin for the plug with working electrode, and the convenience that user carries out electrode plug work is effectively guaranteed.Due to the extremely difficult oxidation of gold electrode, the service life of electric-optically Q-switched DKDP switch is greatly extended, due to using microstress (the releasable structure of stress), greatly ensure that the performance of electric-optically Q-switched DKDP switch.
Description
Technical field
The utility model provides a kind of electric-optically Q-switched DKDP construction of switch of microstress, the component be serve it is electric-optically Q-switched
DKDP switch, and electric-optically Q-switched DKDP switch modulation effect stability, pulse width are small, it is applied widely, it is widely used to more
A laser field.On the total solids electro-optical Q-switching laser as laser medium of Nd:YAG, Nd:YLF, Nd:Glass, electric light
Adjusting Q DKDP switch is one of critical component.
Background technique
Electric-optically Q-switched DKDP switch is to be fabricated to the electric-optically Q-switched of function admirable according to the high characteristic of electro-optic crystal electro-optic coefficient
Device.Its modulation effect is stable, pulse width is small, applied widely, is widely used to multiple laser fields.Nd:YAG,
On the total solids electro-optical Q-switching laser as laser medium of Nd:YLF, Nd:Glass, electro-optic Q switch be critical component it
One.But it after electro-optic crystal generallys use bonding copper electrode in electro-optic Q switch at present, is deposited with the structure type that electrode wires are drawn
, since the operating voltage of electro-optic Q switch is in 3200V or more, copper electrode is easily aoxidized, the copper electrode after oxidation to electric light crystalline substance
The damage of body is very severe, and strong influence has arrived the service performance and working life of electrooptical switching.
Summary of the invention
Purpose of the utility model is to overcome the deficiencies of the above prior art and provide one kind always may be used with longer life
To keep the electric-optically Q-switched electric-optically Q-switched DKDP construction of switch of DKDP switch performance steady operation microstress.
To achieve the above object, the utility model adopts the following technical solutions:
Electro-optic crystal is installed in the electric-optically Q-switched DKDP construction of switch of microstress, including columnar hollow shell, insulation shell inside,
The electro-optic crystal rear ends are coated with gold electrode of the chromium as substrate, and setting communicates on the insulation crust of the electro-optic crystal
Inner groove and outer deep gouge structure place conductive adhesive tape in the inner groove, squeezed in the outer deep gouge gold-plated electrode contact pin and with
The conductive adhesive tape is in contact, and the gold-plated electrode contact pin is equipped with socket.
Preferably, the conductive adhesive tape head and the tail inside the inner groove do not connect, and there are gaps.
The utility model has the beneficial effects that the invention is realized in this way, made using chromium be coated with to electro-optic crystal
For the gold electrode (chromium is the firmness in order to guarantee gold electrode as substrate) of substrate, then on the insulation crust of electro-optic crystal
It designs the outer counter bore structure of inner groove structure and communicates, inner groove places the conductive adhesive tape of reasonable length, the conduction inside deep gouge
Adhesive tape cannot be end to end there are reasonable gap, to be answered in assembling process using the elongation property release contact of conductive adhesive tape
Power, outer counterbore squeeze gold-plated electrode contact pin and are in contact with conductive adhesive tape, and there are sockets on gold-plated electrode contact pin.
Due to the extremely difficult oxidation of gold electrode, the service life of electric-optically Q-switched DKDP switch is greatly extended, due to adopting
With microstress (the releasable structure of stress), therefore it greatly ensure that the performance of electric-optically Q-switched DKDP switch.

Specific embodiment
The utility model is further elaborated with reference to the accompanying drawings and examples, it should explanation, under state
It is bright merely to explain the utility model, its content is not defined.
As illustrated in fig. 1 and 2, the electric-optically Q-switched DKDP construction of switch of the utility model microstress, plates chromium on DKDP crystal 1
As the gold electrode 6 of substrate, the conductive adhesive tape 5 for then using head and the tail not to be in contact carries out contact chromium as the gold electrode 6 of substrate, leads
Electric adhesive tape 5 is placed into switch insulation shell 2, is in contact with gold-plated electrode contact pin 3 biography of electric signal is effectively guaranteed above
It passs, jack structure is devised on gold-plated electrode contact pin 3 for the plug with working electrode, user is effectively guaranteed and carries out electricity
The convenience of pole plug work.
It is above-mentioned although specific embodiments of the present invention are described with reference to the accompanying drawings, but it is not practical new to this
The limitation of type protection scope, based on the technical solution of the present invention, those skilled in the art do not need to pay creation
Property the various modifications or changes that can make of labour be still within the scope of the present invention.
