The typical system structure is as follows: the laser chip is connected to a copper carrier throughHHLEncapsulated form of emission, without collimating lens.TEC（ThermoElectricCooler）Also known as a semiconductor cooler, it utilizes the Peltier effect of semiconductor materials. When current passes through a thermocouple composed of two doped semiconductor materials, one side absorbs heat and the other side releases heat.
