Hi to every one! I'm new in this forum, I'm an 19yo italian laser fun Ok i'm italian so my English is not very good :) :) I was looking for a mid power IR laser diode (about 500mw) to do some engraving on wood and obviously some burning :) I found this...

Hi i've a 150mW blue(405nm) laser diode... I've already done a 150mA power supplier, but I want to make another one that is variable from 10mA to 500mA... 1. Can i do it usin the LM317 and using a trimmer? 2. Does the diode work at a lower level of power (like 80mA) thank :)

Hi!! I'm Davide... So, I've a littel questio :) I want built a little argon ion laser and I want know if I can use Copper to make the tube of the laser... thank you bey :)

oh ..!! thank you... i'm working to make the host with the lens for the collimation... thanks to everybody ... hi!!!

Hi I'm Davide ... I'm italian and I don't write english very well XD ... So. To start a laser you have to excitate atoms with High Voltage ... correct? so can I use an HV inductor and apply a low voltage (for example 20V) to the elettrods? like this thanks ...
