Some manufacturers are selling indicators with parallel blue Laser pointer diodes that measure power over 1500 milliwatts. However, since the claimed power of "laser pointer" products also includes infrared power (only in semiconductor pumping technology) is still in the beam (for reasons discussed below), based on the stricter visual blue DPSS-type components, the laser still exists The problem is usually inapplicable information. Due to the use of higher neodymium harmonics, the frequency doubling conversion efficiency is lower. A small part of the infrared power is in the optimized configuration of the semiconductor pump module. The conversion of the 473 nm blue laser is usually 10-13%, which is about half. Typical of green lasers (20-30%).
Blue laser can also directly produce indium gallium nitride semiconductors to produce blue light without frequency doubling. There are (447±5 nm) blue laser engraver diodes on the market. This device is bright and the same as a violet laser diode with a power less than 405 nm, because the longer wavelength is closer to the peak sensitivity of the human eye. The mass production of laser projectors for commercial equipment, such as laser diodes, has driven prices down. The popular high-power (1W) 447 nm indicator, which also has an improved optical version with better collimation and lower divergence, is comparable to the use of these portable devices and related problems with the intent and cost of human harm has been reduced. Competitiveness of laser wavelength.
When using the laser function, please do not directly irradiate people's eyes, it may cause burns or blindness. In particular, blue laser pointer beams with a power exceeding 5mw directly irradiate human eyes for a long time, and the possibility of blindness is greatly increased. Therefore, we must be careful not to let children play. Please pay attention to the warning sign on the battery cover when purchasing.
