    problems with air (nitrogen) laser

    Hello. Recently I was planning to build an air laser based on information from styropyro and plasmachannel films. The 2 capacitors I built here have 4.5nF each. as a laser gap I used aluminum profiles which I sanded with very fine sandpaper. the spark gap is just a wire and a coin. as a source...

    3D model of laser pointer host for you guys

    thank you! I have also been dealing with 3d printing for a few months and modeling in 3d only for a few days and this case is my first self-made 3d project.

    3D model of laser pointer host for you guys

    One of the most popular 5.6mm diode houseings used by the laser hobbyist is the AixiZ laser module. I thought that not everyone is able to make a nice case for such a laser based on the aixiz module, but maybe he/she have/has a 3d printer, so I designed in FreeCAD a case for such a laser that...

    Sanwu lasers silver series 520nm or 525nm?

    Hello. I have a question. I am saving on the laser from sanwu "silver series" and I wonder if it is better to buy the 1.2W 520nm or 1.2W 525nm version. 520nm is a bit more expensive. as far as I know 525nm will be slightly brighter to the human eye than 520nm. My question is what do you...

    Building 532nm dpss laser

    I just wanted to buy a 9mm 2500mw 808nm laser diode, remove the DPSS crystals from the green laser pointer and buy a housing for such a diode so that you can attach these crystals (such housing as for green lasers only that for a 9mm diode). finding the housing is the biggest problem. Anyway...

    Strange behavior of the red laser

    Hi. I have a question. I recently built a laser from a DVD burner. During the experiments I decided to light this laser in the mirror so that the laser beam reflected back to the laser and at that moment the laser diode got damaged (typical damage of this type of diodes consisting in that they...

    Buying a red laser pointer

    I have a question. Will the usual lens from the 5mw aixiz laser module fit well in this housing and if it is screwed in will the laser beam have the correct shape (such that you do not have to rotate the lens to make the laser point small over large distances)?

    Buying a red laser pointer

    I think I will put an lpc836 laser diode into this housing, thanks to which I will be able to easily reach 350mw at the output and if I quote the manufacturer's recommendations a little bit, I should be able to reach over 400mw at the output, and besides, this diode is very easy to get and is...

    Buying a red laser pointer

    by the way the seller writes that it is a laser that emits a line instead of a dot, but I think it can be easily changed by replacing the lens. Am I right?

    Buying Skylasers or laser btb

    oh ok I also recently had to collect the number of messages to reach 20 to be able to publish links in my messages, but at least I did not do something like this user only honestly tried to help other users on issues that I have a little idea

    100mW Laser, what precautions should I have?

    You should use safety glasses and you shouldn't point it at cars people animals and airplanes

    Buying Skylasers or laser btb

    Hello. About 6-7 years ago I wanted to buy a skylasers 532nm 200mw laser, it was my dream but I was still quite young and I didn't have enough money. The only thing I could afford was a 303 laser. Now when I can afford to buy such a laser, skylasers no longer offers this model. This is really...
