What the utility model adopted is more reliable indirect water-cooling mode, form is flexible clamping indirect water-cooling formula, provides cooling to the KTP frequency-doubling crystal.
Common indirect water-cooling mode is a rigidity clamping indirect water-cooling mode, frequency-doubling crystal separates with the water flowing chamber, (Fig. 1～Fig. 3) is formed by fixture block up and down in the water flowing chamber, frequency-doubling crystal is with the clamping of screw rigidity, and rotating part is that two semicircular ring structures are closed up the rotatable adjusting in rotary connector of back formation complete circle structure.Characteristics: simple in structure, good cooling results is for ease of maintenaince changed crystal.Shortcoming: safety inadequately.Frequency-doubling crystal work the time will produce a large amount of heats, crystal generation thermal expansion, and the heat conduction meeting is inhomogeneous, and the rigidity clamp structure of directly tightening with screw can hinder the thermal expansion of crystal, forms extruding, thereby causes crystal fracture.The rotating part that is made of two semi-circular structure also is a rigid structure in addition, can not open during work, and this also can hinder the thermal expansion of crystal, forms hidden danger.
Summary of the invention
The utility model purpose: be in order to remedy the defective of prior art, to have absorbed the advantage of traditional indirect water-cooling mode, providing a kind of device of flexible indirect water-cooling formula clamping frequency-doubling crystal, safety when well having solved the crystal thermal expansion.
To achieve these goals, the technical solution of the utility model is such: it comprises adjusts mirror holder 1, Rotary Connection block 8, dog screw 9, water nozzle 10, water nozzle nut 11, sealing ring 12, connection water pipe 13 and clamp structure, it is characterized in that clamp structure is to use fixture block 2 will believe that by the screw 5 of cover compression spring 4 crystal 6 is realized the flexible stabilization clamping frequently with following fixture block 3; The retaining part of last fixture block 2 is more smaller than following fixture block 3, makes the suitable minim gap Δ t≤1mm of reservation between the upper and lower fixture block; An end face of following fixture block 3 is provided with a cylinder ring, with holding screw 7 the cylinder anchor ring of Rotary Connection block 8 with following fixture block 3 is fastenedly connected, constitute integrative-structure, again integrative-structure is pushed in the rotation installing hole of adjusting mirror holder 1 centre, make its location with dog screw.Form the form (Fig. 3) of clamping crystal by last fixture block and play fixture block, the design of following fixture block has integral type cylinder ring structure (Fig. 2).To go up fixture block and following fixture block produces flexible chucking power with spring and comes the clamping frequency-doubling crystal.Upper and lower fixture block is the water flowing cooling chamber, connects with connecting water pipe, and water flowing forms boiler water circulation, realizes the purpose that the heat that frequency-doubling crystal produces is taken away.
The minim gap Δ t≤0.5mm that goes up between fixture block and the following fixture block described in the utility model.
The utility model has the advantages that: the safety problem when adopting flexible clamp structure to solve the frequency-doubling crystal thermal expansion also keeps the easy replaceability of crystal.Be characterized in: simple in structure, good cooling results, safety and stability, the good adjusting, the good replacing, compatibility is good, satisfies the needs of general optical application fully.

Embodiment
The utility model in conjunction with the accompanying drawings 1 to 5 is described in detail as follows to its technical scheme:
Clamp structure is installed in to be adjusted on the mirror holder 1, can adjust the angle of pitch.Clamp structure is to use fixture block 2 by the screw 5 of cover compression spring 4 frequency-doubling crystal 6 to be realized the flexible stabilization clampings with following fixture block 3.With holding screw 7 the cylinder anchor ring of spill spin block 8 with following fixture block 3 is fastenedly connected, constitutes integrative-structure.Integrative-structure after will connecting again pushes the rotation installing hole in the middle of the adjustment mirror holder 1, make its location with dog screw 9, adjust by it being carried out 360 ° of rotations, so just can carry out the comprehensive adjustment of phase angle and deflection, to reach the maximum of double-frequency laser to frequency-doubling crystal 6.Certainly also can match the four-dimensional mirror holder of adjusting, realize five dimension adjustment; If it is whole to carry out the anteroposterior position transposition of mirror holder on this, just realized sextuple adjustment.
In order to allow frequency-doubling crystal and closely subsides mutually of fixture block up and down, wrap one deck indium film (expressing among the figure) at the crystal 6 sidewall, in order to effective increased thermal conductivity energy.To go up fixture block 2 in addition is designed to, the form more smaller than the retaining part of following fixture block 3 keeps suitable minim gap Δ t≤1mm (shown in Figure 5), and representative value is 0.5mm, better contact in the time of can making crystal be subjected to clamping, further strengthen the heat conductivility of each face of crystal with wall; And can compensate the dimensional discrepancy that produces in the manufacturing.External refrigeration water siphunculus road enters from upper end water nozzle 10, with water nozzle nut 11 that line seal is good, seal with sealing ring 12 between water nozzle 10 and the fixture block, cooling water is by behind the last fixture block 2, be connected to down fixture block 3 with connecting water pipe 13, flow out from lower end water nozzle 10 then, finish a cool cycles of taking away heat.
The material selection of last fixture block 2 and following fixture block 3 be corrosion resistance, thermal conductivity all preferred metal as basis material; Water nozzle part the selection of material is a common stainless steel; Sealing ring is selected silica gel O type circle for use.
This structure is more convenient when the repair and replacement crystal, owing to adopt the flexible structure clamping, the crystal thermal expansion that has produced when effectively having avoided adopting the rigid structure clamping bursts problem.Selection simultaneously is suitable, has guaranteed cleannes and the sealing property and the ageing resistance in water route.How many variations are outward appearance do not have to take place from this structure of volume and traditional indirect water-cooling mode, but the variation that the details of internal structure and material produces makes crystal obtain stable cooling effect, thereby make the good embodiment of arriving of its optical property.
Actual use and common chamber in, the cavity external frequency multiplication mode is just the same, can realize replacing fully, need not to transform in addition, directly application gets final product.
