What do "mW" and "nm" mean?
mW stands for milliwatt, a measure of energy. nm stands for nanometer, a measure of length. In lasers, mW is used as a unit to describe the power of lasers. Basically the higher the power, the brighter the dot and beam will be. Also, with more power comes more burning capability. nm refers to the wavelength of the laser. Wavelength can basically be thought of as a very specific color. Common wavelengths you will see here are 405nm (violet), 473nm (blue), 532nm (green), 593.5nm (orange/yellow), and 650-670nm (red). This is a good illustration of the visible spectrum.
