3500mw blue laser pointer button issue
1. First of all, please make sure the batteries work well and installed correctly.
Use 2 x 16340 or 2 x 18650 or 2 x 26650;
Positive to laser head;
Never use 3 batteries together;

2. Use a 5V USB wire test the laser head.
Remove the battery tube compartment, there is a interface can connect the 5v USB power.
3. Tight the end cap.

Different laser wavelengths which band burning something stronger?
Different laser wavelengths which band burning something stronger?
405nm has the most powerful to burn object, but portable laser cannot be made to very high output, low beam light, even cannot be seen in daytime.
2W near infrared is very powerful, but divergence, beam spot almost invisible;
The high power of 532/635/650nm, can be long distance to burning object, the effect much better than blue.
445nm, single photon energy is very high, so as power, short distance burning is the best, but the burning ability will decline when the distance being longer, but with the increase of output, the long distance burning effect will gradually catch up the low power of green.
Different wavelength has different light emitting principle.
Different wavelength has different light emitting principle.
532nm is pumped laser;
445nm is a semiconductor laser, efficiency is relatively high;
532nm is pumped by a 808nm, so the efficiency is low;
445nm is direct emitting by a 445nm diode;
Blue light emitting easily, it can light directly after add the lens alignment.
532nm required to process very high technical.
Which color laser beam brightest?
Which color laser beam brightest?
Human eye is most sensitive to green light.
So the same power laser beam, green laser beam is the brightest.
