Have you all heard of pumping lasers? Its English name is pump laser, which is a laser that uses the pump energy to stimulate the laser to amplify the medium (such as crystals, glass, gas, etc.) to produce laser emission. The pump laser is composed of laser medium, pump source, resonator, output coupler and controller, etc. It is mainly used in industrial, medical, communication, information technology and other fields, such as manufacturing micromachining, clinical treatment, optical communication, measurement and lidar. It uses a laser as a pump source and provides energy through a semiconductor laser. This energy is absorbed by the laser medium, such as ytterbium-doped fibers or crystals, and excites electrons in the medium. Through the above process, the final output of high power and high quality laser is generated.   ▲ Pump laser working principle   【980nm pump...

Thermoelectric refrigeration is a solid-state refrigeration technology based on the Peltier effect, which mainly uses the properties of P-N junctions in semiconductor materials. Its characteristic is that when the current flows between the N-type and P-type materials, heat is transferred from one end of the cooler to the other. Because the N-type material has excess free electrons, and the P-type material has insufficient electrons, the excess electrons in the N-type material and the "holes" in the P-type material become carriers. When the carrier moves, the heat then passes through the thermoelectric element, creating a cold and hot temperature difference between the top and bottom of the device. It is worth mentioning that because the phenomenon is completely reversible, when the polarity of the DC power supply changes, the heat will be transferred in the opposite direc...
