The tube lamp flashed an intense white light that chromium atoms in the ruby ratified. Since the atoms lose energy, released photons transferred between the mirrors, stimulating more atoms, before they finally escape from one end of the rod in short pulses of red light.They can be red, blue, green laser pointer.Use laser pointer buy, you can see a few hundred meters away from the place, so often use laser pointer.The majority of the current laser pointer green, red and blue is relatively small, but expensive.
