2V so they're great for your embedded electronics project. This particular module has a lens attached that will turn the dot into a cross. This makes it particularly good for laser-vision guidance, targeting, and more!A laser diode (LD, also injection laser diode or ILD or semiconductor laser or diode laser) is a semiconductor device similar to a light-emitting diode in which a diode pumped directly with electrical current can create lasing conditions at the diode's junction. : 3 Driven by voltage, the doped. The term LASER stands for Light Amplification by Stimulated Emission of Radiation. It functions similarly to an LED, but the key.
