Description
Technical field
The present invention relates to heat radiation and the fixing method of a kind of laser diode end-face pump solid laser (DPL), particularly laser diode end-face pump solid laser crystal.
Technical background
Because the existence of crystal thermal effect, the output stability and the brightness of solid state laser (DPL) have been had a strong impact on, application for solid state laser (DPL) is very unfavorable, therefore, should fully take into account the efficiently radiates heat of crystal in the time of design solid state laser (DPL), reduce the adverse effect of thermal effect as far as possible; In addition, consider crystal in assembling process, must apply enough chucking powers, just can guarantee the locking of solid state laser (DPL) system crystal attitude in complicated external environment, have good environmental suitability.In brief, a key problem that will solve in solid state laser (DPL) system design process is exactly how to guarantee can fully dispel the heat under the firm clamping situation of crystal.
Summary of the invention
The heat radiation and the fixing method that the purpose of this invention is to provide the little laser diode end-face pump solid laser crystal in a kind of simple in structure, coated metal and plane of crystal gap.
Technical scheme of the present invention is to realize like this, the heat radiation of laser diode end-face pump solid laser crystal and fixing method, it is characterized in that: the crystal that constitutes laser diode end-face pump solid laser is that cross section is square YAG crystal, square YAG crystal is by the clamping of two L type metal derbies, constitute a tetragonal body, again by the clamping of U type metallic channel, U type space has pair of metal to split regulating one on the other, is used to eliminate the spatial joint clearance in its U type space around the tetragonal body.
Described tetragonal body is by the outer U type metallic channel clamping that becomes 90 degree, and U type metallic channel is placed in the U type space of outer U type metallic channel, and each U type space has pair of metal to split regulating one on the other, is used to eliminate the spatial joint clearance in its U type space.
Described square YAG crystal volume is 3mm * 3mm * 5mm or 5mm * 5mm * 10mm.
Advantage of the present invention is: owing to constitute the crystal of laser diode end-face pump solid laser is that cross section is square YAG crystal, square YAG crystal is by the clamping of two L type metal derbies, constitute a tetragonal body, around the tetragonal body again by the clampings of two U type metallic channels that are mutually 90 degree another, one of them U type body is placed in the U type space of another U type metallic channel, each U type space has pair of metal to split, split effectively eliminating the gap between two L type metal derbies and the square YAG crystal by adjusting metal, reach the purpose of abundant heat radiation.
Description of drawings
The invention will be further described below in conjunction with the embodiment accompanying drawing:
Fig. 1 is embodiment 1 structural representation;
Fig. 2 is embodiment 2 structural representations.
Among the figure, 1, square YAG crystal; 2, L shaped metal derby; 3, metal split right; 4, U-shaped metallic channel; 5, outer U type metallic channel.
Embodiment:
For fit shown in Figure 1: at first can be 2 clampings of square YAG crystal 1 usefulness pair of L type metal derby with cross section, the optical direction equal in length of L shaped metal derby 2 thickness and square YAG crystal 1 increases the contact area of dissipation that looses to greatest extent; Secondly, there are pair of L-shaped metal derby 2 integral body of square YAG crystal 1 to place U-shaped metallic channel 4 clamping, bottom surface and the inner left wall of being close to U-shaped metallic channel 4, and the space between the inwall of right side is split with metal and is filled 3, utilize metal to split the slide relative between 3 with a pair of lateral surface compressing of L shaped metal derby 2 with square YAG crystal 1, guarantee that the crystal clamping is fastening, when metal being split to 3 application of forces, to the L shaped metal derby 2 downward application of forces in upper end, make square YAG crystal 1 outwards to dispel the heat by four sidewalls.Under this kind fit, square YAG crystal 1 has only the clamping of a pair of side fastening, secure heat dissipation.
Shown in Figure 2, equally at first can be 2 clampings of square YAG crystal 1 usefulness pair of L type metal derby with cross section, the optical direction equal in length of L shaped metal derby 2 thickness and square YAG crystal 1 increases the diffusing area of dissipation of contact to greatest extent; Secondly, there are pair of L-shaped metal derby 2 integral body of square YAG crystal 1 to place U-shaped metallic channel 4 clamping, bottom surface and the inner left wall of being close to U-shaped metallic channel 4, and the space between the inwall of right side is split with metal and is filled 3, utilize metal to split the slide relative between 3 with a pair of lateral surface compressing of L shaped metal derby 2 with square YAG crystal 1, guarantee that the crystal clamping is fastening, when metal being split to 3 application of forces, to the L shaped metal derby 2 downward application of forces in upper end, after this, whole being placed on again in the big slightly outer U type metallic channel 5 re-uses metal and splits and to 3 it is compressed.This fit makes pair of L-shaped metal derby 2 press four sides of square YAG crystal 1, thereby realizes the secure heat dissipation and the firm clamping of 1 four sides of square YAG crystal.Realize crystal and extraneous reliable clamping and outside unimpeded heat conduction.
Square YAG crystal 1 volume can be selected 3mm * 3mm * 5mm or 5mm * 5mm * 10mm, need select to use.
Embodiment of the present invention is simple, is particularly suitable for solving the clamping problem of the square laser crystal of small size, and bond is split right, can farthest utilize the outside heat conduction of crystal sidewall when realizing firm clamping.It is very easy that L shaped metal derby is made, and processing cost is low.
It is pointed out that this design is equally applicable to the crystal that cross section is a rectangle.
