Abstract
The utility model relates to a suspended semiconductor refrigerating laser temperature control device, which comprises a temperature sensor and a temperature control unit connected with each other. The suspended semiconductor refrigerating laser temperature control device provided by the utility model has stable output luminous power, high reliability and convenience in use.
Description
Technical field
The utility model relates to a kind of attemperating unit, relates in particular to a kind of unsettled semiconductor refrigerating laser temperature control device.
Background technology
Laser is a kind of optical frequency electromagnetic wave, because it has good directivity and monochromaticjty, so its brightness height, the angle of divergence is little, the coherence good and frequency is very high.These excellent characteristic of laser make it in important effects of many fields play more and more such as optical communication, optical information processing, optical measurement, printing, holography, buildings.Though it is relatively good that green laser has collimation, the visual brightness advantages of higher, the generation of green glow is direct unlike red laser or infrared laser to be produced by the laser chip pumping, but with the infrared laser of 808nm, the 532nm green glow that produces by crystal double frequency.And this crystalline material is relatively more responsive to ambient temperature, and generally about 23 ℃, operating state is best.Ambient temperature is too high or too low, all the crystals lattice structure is changed, thereby has influence on the resonance effect of laser in resonant cavity, directly causes the stable variation of green glow power output, makes the suitable environment temperature conditions of green glow product require than higher.
For in high-power laser and corresponding use scope, its key technology is that green laser is to produce by the pumping of operation material crystalline material, the stability of its Output optical power, influenced by ambient temperature bigger, this is the bottleneck problem that whole laser industry faces.This problem has two aspects, on the one hand is that the pump laser source optimum state of double-frequency laser is wavelength 808nm, but after producing heat when work with laser tube, wavelength is elongated with the temperature rising, causes the double-frequency laser power drop; Be that operation material crystal optimum Working is about 23 ℃ on the other hand, too high or too low for temperature, its internal crystal framework tissue deforms, thereby causes the instability of power output.
The utility model content
In order to solve the above-mentioned technical problem that exists in the background technology, the utility model provides that a kind of Output optical power is stable, reliability unsettled semiconductor refrigerating laser temperature control device high and easy to use.
Technical solution of the present utility model is: the utility model provides a kind of unsettled semiconductor refrigerating laser temperature control device, and its special character is: the temperature control unit that described unsettled semiconductor refrigerating laser temperature control device comprises temperature sensor and links to each other with temperature sensor.
Above-mentioned temperature control unit is cooling piece or heats sheet.
Above-mentioned unsettled semiconductor refrigerating laser temperature control device also comprises fin, and described fin links to each other with cooling piece.
Above-mentioned cooling piece is a semiconductor chilling plate.
The said temperature transducer is a temperature sensing resistor.
The utility model has the advantages that:
1, Output optical power is stable.The utility model with pump laser source and laser crystal as assembly after, unsettled and semiconductor chilling plate bonds together, make pump laser source and laser crystal avoid contacting with radiator portion, thereby make whole effects of semiconductor chilling plate all act on pump laser source and the laser crystal, improved refrigeration and the effect that heats up greatly, can under the operational environment of wideer temperature, stablize power output to satisfy laser.This refrigerating plant can make the pump laser source of work in the laser high-power, big electric current and laser crystal fully be cooled off or heat up, and makes that stream time obtains prolonging, and power stability promotes greatly.
2, the reliability height is easy to use.The heat that the frequency multiplication green-light source that unsettled semiconductor refrigerating laser temperature control device provided by the utility model is provided, its internal heat resource produce when mainly being laser tube work.This unsettled semiconductor refrigerating laser temperature control device is to carry out temperature control by semiconductor chilling plate, 808nm pump laser source and frequency-doubling crystal and shell radiator portion are carried out heat isolates, and adopt semiconductor chilling plate to carry out the processing of thermal source, be connected by the positive and negative of semiconductor chilling plate, the 808nm laser tube is freezed or heats.Under the low temperature environment, laser tube is carried out The pre-heat treatment, can reach normal operating conditions fast, when ambient temperature reaches certain value in the 808nm laser tube, automatically lead phase, freeze, the interior ambient temperature of 808nm laser tube is remained in the suitable temperature range, this refrigerating plant can make the pump laser source and the laser crystal high-power, big electric current of working in the laser fully be cooled off, and makes that stream time obtains prolonging.If controlled, can guarantee that then crystal, laser tube and semiconductor chilling plate are not damaged, and power stability promotes greatly, and make the ambient temperature range when having the refrigerating plant laser works improve greatly by temperature-control circuit.The utility model is the integrated design, and has advantages such as volume is little, reliability is high, easy to use.
Description of drawings
Fig. 1 is the structural representation of unsettled semiconductor refrigerating laser temperature control device provided by the utility model.
Embodiment
Referring to Fig. 1, the utility model provides a kind of unsettled semiconductor refrigerating laser temperature control device, the temperature control unit that this device comprises temperature sensor and links to each other with temperature sensor, this temperature control unit can be cooling piece or heat sheet, if when adopting cooling piece, this unsettled semiconductor refrigerating laser temperature control device also comprises fin, and fin links to each other with cooling piece.Cooling piece can be that semiconductor chilling plate 5 or the refrigeration part identical with its effect all are the same effects.Temperature sensor is a temperature sensing resistor 3.
The utility model in use, at first with the utility model and laser, especially the pump laser source 2 of green (light) laser links to each other, when temperature sensor obtains the temperature of pump laser source 2, can adjust the temperature of pump laser source 2, perhaps cooling or intensification makes it can reach best result of use.
Unsettled semiconductor refrigerating laser provided by the utility model, refrigerating plant mainly comprises semiconductor chilling plate 4, temperature sensing resistor 3 and fin 6, and pump laser source 2 etc.Compare with general refrigeration semiconductor laser, existing unsettled semiconductor refrigerating laser temperature regulating effect has improved a lot.As that pump laser source 2 and laser crystal 1 is not isolated with radiator shell 5, the two ends temperature difference of semiconductor chilling plate 4 will be dwindled, because the temperature on the radiator 6 can be by importing the upper end of semiconductor chilling plate 4 into pump laser source 2 and laser crystal 1 part once more, thereby will have a greatly reduced quality at the refrigeration or the intensification effect of pump laser source 2 and laser crystal 1.
