Abstract
The utility model relates to a positive-column helium cadmium laser which is used for the fields of fluorescence excitation, stereo rapid tooling, holograph, picture element holograph, etc., and is composed of side plates, steel pipes, a laser discharge tube, a tantalum sheet, a bracket, a gas storage cylinder, a heat-insulating cover, fixing frames and a cavity adjusting frame. The utility model is characterized in that the four indium steel pipes are connected into a frame structure via the side plates on both sides and the three fixing frames in the middle; the laser discharge tube is fixed on the three fixing frames provided with fine setting screws abutting on the partial laser discharge tube; the discharge tube part in the middle is provided with the heat-insulating cover outside; the tantalum sheet is fixed on the bracket. The laser has the advantages of high stability, small size, light weight, convenient carrying, and application to small matched instruments.
Description
Technical field
The utility model relates to a kind of positive column type helium cadmium laser that is used for fields such as fluorescence excitation, three-dimensional rapid die-manufacturing, holographic, pixel holography.
Background technology
Helium cadmium (He-Cd) laser output 441.6nm wavelength just is being that application is quite extensive in the high sensibility spectral region of receiver.As fields such as fluorescence excitation, three-dimensional rapid die-manufacturing, holographic, pixel holographies.In recent years, along with the application of helium cadmium laser constantly enlarges, especially certain demand was arranged in microelectric technique, CD burning and laser and/write system.But requirement has been proposed for laser miniaturization and output power stability.Yet, laser tube in the existing laser normally is fixed on the seamless steel pipe support of a φ 70mm, steel pipe is to play the fixed support effect, in order to guarantee the stability of laser output, adopted the round steel of 8mm wall thickness, such laser weight increases, and volume increases, and can not satisfy the requirement of miniaturization.
Summary of the invention
The purpose of this utility model is in order to overcome existing helium cadmium laser Heavy Weight, bulky shortcoming, a kind of positive column type helium cadmium laser of miniaturization of compact conformation to be provided.
The technical solution of the utility model is: it is made up of other plate, steel pipe, laser tube, tantalum piece, support, gas bomb, stay-warm case, fixed mount, chamber regulating frame, be characterized in, it is by four indium steel pipes, other plate and three middle fixed mounts by both sides connect into closed-in construction, laser tube is fixed on three fixed mounts, be equipped with on the fixed mount fine adjustment screw in the laser discharge tube portion near, middle discharge tube part is outer to be equipped with stay-warm case, tantalum piece is fixed on the support.
The utility model frame structure of indium steel pipe, because the indium steel coefficient of expansion is little, near the glass swelling coefficient, laser tube is a heater, therefore improves stability, the fine adjustment screw that is equipped with on the support greatly, can the collimation laser discharge tube, make laser tube stablize bright dipping, stay-warm case makes the laser tube tube wall temperature constant, avoids the cadmium vapor condenses on the tube wall of laser tube.With the structure of such scheme, the stability of pipe can guarantee equally, and the laser volume reduces, and weight saving is easy to carry, is highly suitable on the small-sized supporting instrument.
