Almost enjoying a green laser pointer has been buying exotic blue for years on the Internet. First, for decades, red laser pens and isolated green lasers can be bought, but blue laser pointer are good for home use. At the same time, there has been a change, and you can even get your presentation to spend money under the blue light. As with all approved Pointers in this country, the available power is less than 1 milliwatt, which is sufficient to be used as a luminous marker or general adjustment and investigation. However, in the blue variant, if the wall is visible, even under the sun, it is necessary to pay attention to the quality of the equipment.Evolution has made sure our eyes are fully adapted to the sun. This includes more green part of our visual sense organs greener, why to show…

Fiber lasers pen have become a hot topic in laser physics research in recent years, and it has been agreed that it is possible to fully replace a new generation of blue lasers pointer. In the process of vaporization, the workpiece table and under the action of the focused laser pointer 500mW beam, the temperature rapidly rises to the vaporization temperature, and the material is vaporized in large quantities, and the high pressure steam is formed by supersonic outward injection. At the same time in the laser area to form a "hole", the laser beam in the hole several times to reflect the material and the absorption of laser abundance quickly increased. Fiber lasers refer to lasers pointer doped with rare earth element glass fiber as a gain medium. When appropriate to join the positive feedb…
