Brightness is one of the important indicators to measure the comprehensive performance of lasers. The fine processing of metals also puts forward higher requirements for the brightness of lasers. Two factors affect the brightness of the laser: its self factors and external factors.
The well-known laser types have fiber laser, ultraviolet laser and CO2 laser, but what is high brightness laser? Let's start with the four basic characteristics of lasers. The laser has the characteristics of good directionality, good monochromaticity, good coherence, and high brightness. The brightness represents the brightness of the laser, which is defined as the light power emitted by the light source in a unit area, a unit frequency bandwidth, and a unit solid angle, Simply put, it is "the power of the laser per unit space", measured in cd/m2 (read: candela per square meter). In the laser field, the laser brightness can be simplified as BL=P/π2·BPP2 (where P is the laser power and BPP is the beam quality).
Brightness is one of the important indicators to measure the comprehensive performance of lasers. The fine processing of metals also puts forward higher requirements for the brightness of lasers. Two factors affect the brightness of the laser: its self factors and external factors.
The self factor refers to the quality of the laser itself, which has a lot to do with the laser manufacturer. The lasers of big brand manufacturers are of relatively high quality, and they have also become the choice of many high-power laser cutting equipment.
External factors refer to the refrigeration system. The industrial chiller, as the external cooling system of the fiber laser, provides constant cooling, keeps the temperature within the suitable operating range of the laser, and guarantees the quality of the laser beam. The laser chiller also has a variety of alarm protection functions. When the temperature is too high or too low, the laser will first issue an alarm; let the user start and stop the laser equipment in time to avoid the abnormal temperature affecting the laser cooling. When the flow rate is too low, the water flow alarm will be activated, reminding the user to check the fault in time (the water flow is too small, which will cause the water temperature to rise and affect the cooling).
S&A is a laser chiller manufacturer with 20 years of refrigeration experience. It can provide refrigeration for 500-40000W fiber lasers. Models above 3000W also support Modbus-485 communication protocol, support remote monitoring and modification of water temperature parameters, and realize intelligent refrigeration.
