Laser output control is mainly controlled by GATE signal; The specific frequency, power and other parameters of the output light are controlled by the PWM signal, mainly to change the frequency cycle and duty cycle in the PWM.Duty cycle: that is, the ratio of the high level holding time to the PWM clock cycle time in the output PWM signal.F...
2023-02-0442400Laser processing equipment is a kind of intelligent numerical control machine tool. Its principle is that high energy density laser is irradiated on the material after being focused by the lens to quickly melt the vaporized material, so as to complete cutting, carving, marking, welding and other processing requirements. Compared with traditional pr...

2023-02-0431500Recently, researchers at the University of Strathclyde in Scotland, UK, have created a laser-driven "mirror", which can reflect or manipulate light.At present, the volume of building space occupied by some ultra-high power lasers is almost the size of aircraft hangar. Although this "mirror" only exists for a short time, it can help reduce t...
2023-02-0341600The high pressure alarm of water-cooled industrial water chiller is mainly caused by the problem of cooling water, especially the cooling water tower, which must be cleaned and maintained regularly. If the water quality is poor, it is better to do water treatment first.The chiller is a cooling water equipment that can provide constant tempe...
2023-02-0348000Although industrial water chillers have been widely used in plastic industry, electronics industry, electroplating industry, machinery industry, construction industry, vacuum coating industry, food industry and many other industries, many enterprises still do not know how to choose and purchase appropriate industrial air water chillers? Here is how...
2023-02-0342500The characteristics of such devices as motors have a great impact on their operation effect and functional performance. Stepping motors have excellent performance in operation and play an advantageous and distinctive role because of the following characteristics:Feature 1: The stepper motor must be driven before it can operate, and the drive model ...
2023-02-0340300Micromotor typeMicromotors are divided into 13 categories, including DC motors, AC motors, synchro motors, stepper motors, rotary transformers, shaft angle encoders, AC and DC dual-purpose motors, tachogenerators, inductosyn, linear motors, piezoelectric motors, motor sets and other special motors.1. Brushless DC motorIt is the fastest grow...
2023-02-0344800For the drive belt pulley, the timing belt pulley is very important. Because of the addition and existence of the timing belt pulley, the drive belt can operate normally. The synchronous pulley is an integral part of the drive belt system. Most of the machinery driven by belt is small wheel with big wheel. This is because the rotating speed ...
2023-02-0343200(1) For high-speed, high-power and long-term working conditions, the transmission system with high bearing capacity, stable transmission and high transmission efficiency should be selected.(2) In the case of low speed, medium and small power and high transmission ratio, multiple schemes such as single-stage worm drive, multi-stage gear driv...
2023-02-0339700In cooperation with physicists from the Max Planck Institute of Quantum Optics and the University of Munich in Germany and scientists from Stanford University, laser was used for the first time to control the position of photo-induced reaction on the surface of nanoparticles.Controlling the strong electromagnetic field on nanoparticles is the key...
2023-02-0338700Recently, Vector Photonics, a laser developer based in Glasgow, UK, announced that it had obtained the latest round of equity investment of more than 2.4 million pounds to further commercialize its unique all-semiconductor photonic crystal surface emitting laser (PCSEL) technology.It is reported that Clean Growth Fund is the leading investo...
2023-02-0341000On February 1, Chromacity, a laser pioneer based in Edinburgh, Scotland, announced a strategic cooperation agreement with Edmund Optics, an American optical technology supplier, which will become the global supplier and distributor of the former's ultra-fast lasers. In the future, Chromacity will actively promote and distribute its fixed-wavelength...
