    My First Laser Build

    Okay so I know it might not be the best looking laser build or most efficient... But this is my first laser build so I can only improve from here. I wanted the laser to be my own and be able to tell people I made it myself. So I made a linear driver using a LM1085 (despite everyone telling me...

    Help with laser build

    Alright so I have built a linear driver using a LM1085 voltage regulator and 2x 1 ohm resistors in parallel using a m140 2w laser diode being ran by 3x 3.7v 2500mAh 18650 (from panasonic). (also has a cool missile launch style rocker switch :D) Here's kind of a picture of what i have so far...

    Ebay laser combiner?

    I found this on ebay and was wondering what the likely-hood of it actually working with a m140 445nm laser diode putting out 2W-2.14W? http://www.ebay.com/itm/331101469581 I don't know anything about optics but from what i'm told you have 2 beams go in and 1 goes through while the other gets...

    Help with driver math calculations

    I am working on making a laser. I bought the 2W 445nm M140 Blue Diode in Copper Module laser diode from DTR's laser shop. I am now wanting to make a driver for the laser. Here is what i know, (or think i know..?) I need 2 Watts to power the laser diode The laser diode can not exceed 1.8...

    I want to build a laser...

    Ok I'm looking to build a laser and have no experience at all. I was wondering if anyone knows any good guides/tutorials. I'm looking for something that can be built from parts off the internet and has links to the parts or names of the parts included and is fairly cheap. I was looking to build...
