Hello, I am looking at building a CNC mill enclosure that can be partially seen through to know things are ok on my mill while it is running a laser engraving head, using both a 445nm high power and the 900mW 405nm lasers for different applications, so I am wondering if there is a source for...

little searching seems to show that it is probably a deformed lens then, :( oh well I guess I am using 405nm frequencies anyway from what I read about CNC use issues of the 445 vs the 405 since now 405 power output is not as shabby as it was when the articles were first written. and no I am not...

by the way the reason I even came to this thread is because I saw the first image (in the OP) in a google search on combining multiple lasers together as one laser. I am very grateful I read the whole thread lol, it would have sucked to try and combine 6 laser together only to find out the cubes...

so I am guessing using quarter wave rectifying layer material in the polarizing process would have zero effect or are they already being used and tuned to the frequency of the laser to ensure low loss of power? can you point everyone to a good article (science article) that explains more about...

can anyone tell me what the "divergence" of a diode means? is this just a term for having a wider array of frequencies it produces? I saw this picture on an auction that directed me here, for a laser I am very interested in due to the color and power, for a project but I want to make sure...
