Abstract

The invention discloses a vertical cavity surface emitting laser for oxygen detection and specifically relates to the technical field of oxygen gas concentration measurement. The vertical cavity surface emitting laser comprises a shell, a display screen is embedded in the surface of the shell, a signal output interface is fixedly arranged at the top end of the shell, a wire is installed in the signal output interface, one end of the wire is fixedly connected with a laser device shell, and a plurality of light-emitting holes are formed in the laser device shell in an annular mode. According tothe invention, the laser chip, the thermistor and the temperature controller are arranged; securing reliability of long-term operation, the working temperature of the semiconductor laser can be tuned,accurate absorption peak wavelength laser can be output, extremely good heat conduction is achieved, the wavelength of the semiconductor laser does not deviate, the protection cover is arranged, theinsertion block is inserted into the insertion groove, installation of the protection cover is achieved, and numerical values in the display screen are observed through the transparent window.

Description

technical field [0001] The present invention relates to the technical field of oxygen gas concentration measurement, and more particularly, to an oxygen detection vertical cavity surface emitting laser. Background technique [0002] Oxygen in the earth is the driving force for the survival of human beings, animals and plants, and the oxygen content in the atmosphere is required to be constant. When the oxygen content in the environment is lower than 21% VOL, it is regarded as anoxic, and when the oxygen content in the environment is higher than 40% %VOL is considered as oxygen-rich, oxygen-deficient and oxygen-rich will poison humans and animals that need oxygen, and even die. At the same time, in order to ensure the safety of production, the production workshop of the oxygen plant and the warehouse where the oxygen cylinders are stored all need to be oxygen-free. Concentration monitoring. [0003] However, in actual use, there are still many shortcomings, such as the wavel...
