Laser beam expander is a lens component that changes the diameter of laser beam and divergence Angle. The laser beam emitted from the laser has a certain divergence angle. For laser processing, a laser beam expander can make the laser beam collimated and obtain a high power density spot after focusing. ... [Detail]

Pre-excitation is also commonly referred to as pre-ionization. The the working gas discharging stably is the basis and premise of the high-efficiency output of the gas laser, and pre-ionization is an effective technical way to achieve the stable discharge of the high-pressure working gas. Because of the gas pre-excitation process, it is necessary to wait for a few seconds for the laser to fire, when every time it is turned on. ... [Detail]
