There are different types of Burning Laser Pointers on the market, so people should always have a clear observation and sufficient basic knowledge before making a decision. For laser enthusiasts, choosing a laser pointer from a reliable supplier and knowing what type of application you need is always a wonderful choice. Please be careful and use a satisfactory laser pointer according to your needs.Most people will be surprised if there are different types of options from various laser pointer suppliers. People should always have a clear observation of the entire laser diode market before making a final decision. How to choose a suitable one? This is really not an easy problem to solve.
Certain wavelength blue laser pointers, such as 473 nm, usually have the same basic structure as the DPSS green laser. In 2006, many factories began to manufacture blue laser modules for mass storage devices, and these modules were also used for laser pointers. These are DPSS type frequency multiplier devices. They usually emit a beam of 473 nm, which is produced by doubling the frequency of the 946 nm laser radiation from a diode-pumped Nd:YAG or Nd:YVO4 crystal (Nd-doped crystals usually produce a dominant wavelength of 1064 nm, but have The correct reflective coating mirror can also be made into lasers with other "high-order harmonics" non-main neodymium wavelengths). For high output power BBO crystal used as a frequency doubler; for lower power, KTP. The Japanese company Nichia controlled 80% of the blue laser diode market in 2006.

These are one of the latest 20000mW color laser pointer 5000mw with a wavelength of 405 nm, only in the visible spectrum. Therefore, these lasers do not look too bright, which makes users feel that they are not as threatening to their eyes. The classification of laser pointers purchased at dangerous distances is based on the risk of injury. Since the laser output is usually a narrow beam, long distances along the beam may be dangerous. An important parameter in laser risk assessment and management is the Nominal Eye Hazard Distance (NOHD). This is the distance from the laser beam directly to the laser opening where the eye will exceed the maximum allowable exposure (MPE) level. Except for NOHD, exposure to laser beams is generally considered not to cause any harm to normal people.
