Description
Technical Field
The invention relates to a device for preventing a shell of an optical fiber coupling semiconductor laser module from generating condensed water, which belongs to the technical field of laser and can be widely applied to a high-power optical fiber coupling semiconductor laser system.
Background
The fiber-coupled semiconductor laser module is a laser in which light emitted from at least one semiconductor laser chip is coupled into an optical fiber through an optical system and is packaged in a housing made of a metal having good thermal conductivity. At least one pair of electrodes on the shell of the laser is led out through an insulator and is used as an energy input channel; at least one optical fiber output on the shell is used as an output channel of the light beam (light energy). The semiconductor laser is the laser with the highest luminous efficiency at present, and with the maturity of the semiconductor laser technology and the reduction of the cost, the application of the optical fiber coupling semiconductor laser module is more and more extensive. Since the semiconductor chip inevitably accompanies energy loss in the process of emitting light, the energy is converted into heat energy, and in order to make the semiconductor laser chip work normally and efficiently, the heat energy must be conducted out in time and efficiently, which is why the optical fiber coupling semiconductor laser module shell needs to adopt a good heat conducting metal material. For some optical fiber coupling semiconductor laser modules with larger power, the bottom of the shell of the optical fiber coupling semiconductor laser module is connected to a cold water plate when the optical fiber coupling semiconductor laser module works. From the view of heat conduction effect, the lower the temperature of the cold water plate, the faster the heat generated in the light emitting process of the semiconductor chip is conducted out, the higher the light emitting efficiency of the semiconductor laser chip is, and the longer the service life of the chip is. However, in practical applications, when the temperature of the cold water plate is too different from the ambient temperature, the moisture in the air will generate condensed water on the housing of the fiber-coupled semiconductor laser module. This condensate water can enter the housing, causing two types of damage to the laser module, one damage to the optics and the other damage to the electrical circuitry. Therefore, the fiber-coupled semiconductor laser module must prevent the generation of condensed water during use, and the current solution is to increase the temperature of the cold water plate, generally the temperature of the cold water is controlled within 10-15 degrees below the ambient temperature, and simultaneously reduce the maximum current of the laser module, i.e. the maximum output optical power. This method is a passive defense and does not fully exploit the efficiency of semiconductor lasers. In use, because a user must frequently adjust the water temperature according to the working environment, the optical fiber semiconductor module is damaged due to slight negligence and misjudgment, and the service life of the laser is seriously influenced.
