For example, a red laser pointer may consist of only a 671 nm laser diode, batteries to power the diode, and a simple lens to collimate the output beam. (Note that this is possible because the laser ...

In the image above you can see the silver cylinder which houses the laser diode. It is focusing the beam on a light dependent resistor to the right which looks almost like a red LED due to the ...

We hate to admit it, but laser cutter beam alignment is no easy task. To greatly assist in this endeavor, though, some folks tend to mix a red diode laser into the path of the beam. Others ...
