It looks like the holiday countdown starts right after Halloween ends. Since Christmas is just around the corner, we've put together a list of 5 awesome gifts you can make with a laser. What color is the most brilliant? Generally, it is important to note that the green laser pointer 532 nm is 7X for 10X more than any other light color with the same power output beam. This means that a 200 mW laser for green is about 7 times more brilliant than any other 200 mW color.
Red 655/650nm is easier to handle and cheaper, albeit with a worse beam profile. This type of diode is generally not suitable for optical combinations of more than two individual diodes, so red power is limited. We use this type of diode in budget systems for a very good price/performance ratio. The red is slightly darker. But you know what? Suppose you have a "perfect" laser pointer: its beam is zero, so the incoming beam is as narrow as it hits the moon as it exits the little device in your hand. Or better yet... imagine an astronaut doing you a favor on the moon: he uses a laser pointer a few centimeters from the lunar surface to illuminate a point.
Second, the laser beam is focused through a large telescope to significantly reduce its spread. A red laser pointer is always a good choice. Smart people want quality high power laser pointer equipment from reliable suppliers. A laser pointer which has a power source (usually a battery) and a laser diode built into the portable device. This emits a very limited coherent low-power laser beam, which is used to highlight something interesting by illuminating it with bright colored dots.
