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...

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...

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...

Hello. I plan to make a 532nm dpss green laser with 500mw output power. could somebody write me exactly what parts I will need? Grettings

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...

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...

Hi I have a question. Do any of you know if Jetlasers sends lasers despite a coronavirus pandemic? I would be very grateful for your answer because I plan to buy a green laser on their website and I do not know if there will be any problems with the shipment.

Hello. I would like to buy a 532nm DPSS green laser pointer with a power of 200mw-300mw. Do you know where I can buy such a laser at a reasonable price? Thank you in advance for your reply and best regards!

Hello. I have a question.Can I use 18650 lithium-ion battery to powerd up lm317 laser diode driver with red laser diode connected? Regards.

Welcome. I would like to buy a red laser (RLF18130), but from what I see it is very difficult to get it. does any of you know where I can buy or own it and would like to sell it to me? I would be very grateful for your answer! regards
