Abstract
The utility model discloses a crystal heat dispersion structure. A metal sealing box (2) is arranged on the outer side of crystal (1); a gap is formed between the side surface of the crystal and the metal sealing box and is filled by liquid thermal conductivity glue (3) after crystal is loaded, so as to ensure that the crystal is in sufficient contact with the thermal conductivity glue and the thermal conductivity glue is in sufficient contact with the metal sealing box; and after the glue is sufficiently cured, the crystal and the metal sealing box are integrally adhered and connected with a heat sink (4). By adopting the structure, the thermal distribution uniformity of crystal can be improved, the heat dispersion state can be improved, the service life of the crystal can be prolonged, the power output can be improved, the assembly stress of the crystal can be reduced, and simple structure and low manufacture cost are realized. The structure is suitable for mass production.
Description
Technical field
The utility model relates to semiconductor laser end-pumped all-solid-state micro-slice laser, the high power radiator structure of optical element outside crystal and the chamber continuously or in the Q-switch laser chamber.
Technical background
Because crystalline host material itself is to the absorption of light energy, the quantum loss, physical mechanisms such as energy jump cause crystal be subjected to that pump light excites, the non-linear conversion of laser, as processes such as adjusting Q crystals in more or less the existence phenomenon of generating heat.Crystal can produce stress deformation, stress birfringence, thermal lensing effect under the effect of heat, when serious even cause the cracked breakage of crystal, these all cause the reduction of crystal optics performance.So in laser design, efficient heat dissipation design uniformly is the key factor of considering when improving laser average power, stability and life-span.
Summary of the invention
The purpose of this utility model is to provide a kind of and improves heat conduction efficiency, improves the heat distribution uniformity to keep the radiator structure of the original optical property of crystal.
The technical solution adopted in the utility model: be provided with the metallic seal box in the outside of crystal, between crystal on side face and the described metallic seal box certain slit is arranged, pack into and pour into heat-conducting glue behind the crystal and fill up the slit, make crystal and heat-conducting glue, fully contact between heat-conducting glue and the metallic seal box, after fully solidifying in glue, again above-mentioned integral body was connected with heat sink being close to, metallic seal box and heat sink be by glue bond, gold-plated, silver-plated or plating indium and heat sink welding, the metallic seal box with heat sink can be simultaneously be close to, the two sides is close to, three faces are close to or be close on four sides.Adopt the utility model structure can improve crystal heat distribution uniformity, improve radiating state, prolong the useful life of crystal, improve power output, reduce the crystal Installation Stress, and simple in structure, cost of manufacture is low, is fit to produce in batches.

Fig. 3 is the 3rd an example structure schematic diagram of the present utility model.
Embodiment
As shown in Figure 1, crystal (1) is installed in the metallic seal box (2) and with seal box and leaves certain slit all around.Packing into pours into liquid heat conductive glue (3) behind the crystal and fills up the slit, makes between crystal and heat-conducting glue, heat-conducting glue and the metallic seal box fully to contact, and after glue such as certain hour or irradiate light fully solidify, above-mentioned integral body is close to heat sink (4) is connected again.Can fix or to paste the side of heat sink (4) in integral body gold-plated by glue between the two, silver or indium make whole welded together with heat sink (4) again by heating.Heat during crystal work is transmitted on the metallic seal box (2) that fully contacts with it by the heat-conducting glue (3) that fully contacts and is transmitted on heat sink (4) again.This radiator structure makes that crystal (1) heat conduction is even, improves thermal conductivity, can prolong the working life of crystal (1) and the overall performance of raising laser.
Fig. 2 is that crystal (1) one side contacts heat radiation with metallic seal box (2), and other three spaces are filled up with heat-conducting glue (3), are close on heat sink (4) again, and the difficulty that installs and fixes that has lowered crystal (1) has also guaranteed good heat radiation simultaneously.
Fig. 3 dispels the heat with the mode that heat sink (4) contact with the bottom surface by a side of metallic seal box (2), with the needs that satisfy and the heat sink cooperation of difformity is dispelled the heat.In addition, this structure can also adopt with three of metallic seal box (2) or four faces and dispel the heat with the mode that heat sink (4) contact.
Claims (3)
1. crystal radiator structure, comprise: the metallic seal box (2) that is arranged on the outside of crystal (1), whole being close to heat sink (4) of metallic seal box is connected, it is characterized in that: between crystal on side face and the described metallic seal box certain slit is arranged, pour into liquid heat conductive glue (3) behind the crystal of packing into and fill up the slit.
2. a kind of crystal radiator structure according to claim 1 is characterized in that: between described metallic seal box (2) and heat sink (4) by glue bond, gold-plated, silver-plated or plating indium and heat sink welding.
3. a kind of crystal radiator structure according to claim 1 and 2 is characterized in that: described metallic seal box (2) can be that one side is close to, the two sides is close to, three faces are close to or the four sides is close to heat sink (4).
