Due to the visibility of the laser beam to the human eye, the 405nm blue-violet powerful high power laser pointer should always pay attention to the necessary working environment. Once the violet-blue laser beam was pointed at a piece of white paper, a few walls produced very bright violet laser spots. Once the blue laser pointer is pointed at a rather hazy work surface, the brightness and visibility of the laser beam may be lower than expected. When you need a laser that shoots a super light, charismatic and charismatic generation, you can always have a laser pointer pointing blue and high brightness. The most attractive blue laser diode beam emits at 450nm, it still produces a blue laser pointer with brighter light. The required blue laser should always have the advantages of high stability and reliability based on the direct emission of a 450nm blue laser diode laser beam.
Several types of laser pointers have made great achievements
Class IIIb and IV laser products are very powerful and can be exposed to laser radiation at any time, which can cause eye or skin injury. Research and industrial lasers and laser show projectors fall into these categories. Class IIIb and Class IV laser projectors may only be sold by or to FDA-approved individuals or companies. For high-brightness fiber laser processing of high thermal conductivity materials, it is best to use a small spot to keep the welding hole stable, but this processing may make the processing process too intense and cause a lot of welding spatter.
Experiments have shown that the high-brightness green laser pointer combined with the high-speed positioning of the remote scanning head can significantly reduce welding spatter, which is achieved by beam swinging to ensure the stability of the welding hole. When welding copper and aluminum, if the beam swing method is not used, the welding spatter will be very serious. Once the high frequency pendulum beam is used, the spatter is reduced. Avoid backlight damage to equipment by installing protective devices. When processing metals with high reflectivity such as copper and aluminum, back light is unavoidable. Due to the natural sensitivity of back light, traditional lasers may cause unstable and destructive automatic shutdown or even scrapping.
