You described your eyes and face burning when in your front yard. It would take a very powerful and expensive laser pointer to do this. A simple laser pointer would not be able to create heat on your skin at a long distance such as across a yard. The most powerful handheld laser currently available [summer 2010] is the 1-watt Wicked Laser Arctic. It can burn skin but at a very close distance, and the burn is very small such as the size of a pea or less.

Aim the laser pointer at the newspaper from a couple of inches away. Press the button to turn on the laser. Release the button when the newspaper begins to smolder from the burning laser you have made. Spray the newspaper with water.Due to its strong straight light, laser pens (pointers) are widely used in teaching, astronomy etc. Just push the button, then you will see striking light shoot. It is alright to point at any targets such as photos, PowerPoint, monitor etc. It may be the proferred choic for astronomy fans, laser fans.

High-powered green laser pointer can burn skin and cause permanent injury to the eyes. If you have a high-powered laser pointer, you can purchase a pair of laser safety glasses or goggles to protect you from it while you’re using it. Laser safety glasses for laser pointers can be bought for use with green lasers, green and blue lasers, and green, blue, and red laser pointers. Essentially, the handheld lasers are a smaller rendition of the portable lasers at lower power output ranges and prices. These lasers are powered by either one or two 16340 lithium-ion rechargeable batteries.

Always first connect the laser diode to the driver, then connect the driver to the battery! Never connect the driver first to the battery - this will kill the diode! Laser diodes are not LEDs, they are very sensitive. Connect the diode to the driver and leave it connected forever, this is the only way to avoid mistakes. This laser can only use 1pcs 18650 lithium battery,other battery doesn't fit it.

Other cells will work but they'll need to be flat top. The mAh in this case won't make too much of a difference as your laser isn't powerful enough to have a huge current draw but in general as mAh increases, continuous output current decreases.

Each specific wavelength, such as laser light emitted by our 532nm green laser pointer, is a specific shade of green. As visible light lasers are only available in very select wavelengths, you’ll see the same numbers repeat itself over and over again on our website. The table below shows the color, wavelength range, and the common wavelengths associated with our lasers.
