Beschreibung
I included a lot of information that I wish I had been able to find
in a video when I first got interested in lasers over a year ago.
Such as basic power requirements of an 808nm 200mW diode and
how to power it up. The laser diode I used in the video doesn't have a photo diode connected to the pin I broke off. I could have left it attached and normally do so even though it doesn't do anything.. By the way most 808nm 200mW laser modules will light a darkened match with 2 AA batteries. 3 AA batteries will usually require a resistor of about .5 ohm to 3 ohm. If you are not lighting a darkened match than your laser is probably putting out something less than 100mW's. Use a multimeter and test current draw of module and make sure it does not exceed stated limit. The driver used here consumes about 20- 30mA's, so since my diode can draw 300mA's safely, then maximum draw of Laser Module should be about 330mA's. If it is too high and you can still safely open module, you can adjust the current on the driver to bring it down. If the module is glued shut than adding a low value resistor (.5 - 3ohms) between batteries and module will do the trick. Most modules you buy will be glued shut and if you try to open them to adjust the current on the driver you will usually end up with a busted something. Also If you want to run the laser module continuously then use a laser module heat-sink. Good luck and wear laser eye protection!
