Hi all. So recently ive just made a 120kv 127mA high voltage dc power supply. With it I plan to make a TEA laser and a throught crossed my mind. Is it possible to pressurise a chamber between the two electrodes with argon gas and expect it to lase with a blue~ light? I find changing the color of...

Hey all. Its my birthday soon and id like to celebrate by bringing a new laser pointer into this world. I would like some help in finding a 1W 5.6mm laser diode, preferably within the blue range for reasonably cheap, hopefully under 30 AUD. Could you help me in finding a laser diode that fits...

Salutations all! I have some questions regarding how much you can push a laser diode resonably. Its quite common practise to run laser diodes at a higher-than-recommended current to squeeze out as much output power from a laser diode. I feel as though this is a stupid question, But whats a good...

Hi all. I recently got a 4W monster laser diode along with its driver and heatsink from dtrs laser shop . However unlike the other projects ive done where there has been no collimator lens, this was does have one. And its preventing me from attatching it to the focus modual (which happens to...

Hi guys. Im interested in building a 125W laser diode array driver to of course drive this absolute monster. I already have some basic experience with other high power lasers under 10W but still experience regardless. Ive build a 3.5W 445nm, 1.2W 535nm, 500mw 650nm, 300mw 650nm, 120mw 532nm...

Hey guys, Laser hobbiest just like you here all the way in australia Our laws are insane regarding lasers, well, atleast for the people like us haha. Where are places i can get high power diodes without customs interviening? And ive seen this law that says if youre part of an approved...

Hey guys. Im very interested in electrical engineering and have already racked up quite a bit of experience in high voltage, and somewhat basic circuits (the grind is real!). And lately for my next project I want to build a new high power laser. Something under a watt for my first project and...
