Test the integrity of a laser diode by constructing a laser pointer using a battery supply. If you really can’t stand to see another ad again, then please consider supporting our work with a contribution to wikiHow. Lasers can easily cause permanent damage to your eyes, even if you only look at the dot. The PSU can be slightly tricky, break it down to the following steps: Clip off all of the white plastic wire connectors. Here is a great video on how to make a laser diode driver. Could I modify these plans to use a green laser diode from a laser pointer with a wavelength of 532nm and a "maximum" output of 240mw (many people have gotten higher power output with this model)? Be careful when soldering the laser diode because laser diodes are particularly susceptible to high heat. You all know that when making a laser device, the most difficult part it's focusing without buying a module. It works by using a driver to regulate the power coming from the laser, and from there the power flows into the diode, lighting it up and producing a lot of light, which can be focused into a single point. Laser diode (mine is red you could buy any color it hardly matters) 10 microfarad 16v capacitor (protects Laser Diode from immediate power supply especially when switching on/off) 1N4007 rectifier diode (protects Laser Diode if batteries are inserted the wrong way ) 2 X 10ohm resistors in parallel ( sets the maximum voltage and current the Laser Diode will get) 100ohm variable resistor (allows fine … The laser diode itself is typically defined by the end-use application and this article assumes the type of laser diode module (hereon simply referred to as a 'laser') is already known. The laser diode consists of a p-n junction where holes and electrons exist. (This process was first proposed in 1917 by Albert Einstein. -A laser diode (no more than 300mW). -make it nice and durable.
