Since waxing monthly tires me out I decided to try Diode Laser. Is it really true that it is much safer than IPL?
For those that have tried, how was the experience? No noticeable hair growth for how long after the recommended sessions?
Thank youu! π€
Recently I bought a diode laser cutter and I am really pleased with it. The problem is that I am in a closed room, it is winter and the smoke is a bit too much. I have planned to build an enclosure with a fan and a duct to get the fumes outside through a window, but I don't want the people walking next to my home to think that something is getting burned and calling the police. That's why I am thinking to add some kind of really basic air filter. Searching on the internet I haven't found too much about the topic. How do you handle the smoke? any suggestions?
EDIT: My laser cutter is a sculpfun s9, ti has a protective tube around the laser tip. It looks like this:
That tube is 1mm over the piece and it can be adjusted. Do you think that using something like an inverse air-assist would work or do I need a full enclosure?
I'm using Neje N40630 (~7,5W single diode) module and diy air assist at about 1 bar/ 14psi pressure. It makes clean cuts but it's painstakingly slow when cutting through 3mm (1/8") baltic birch veneer.
I'm running it at 4mm/s (240mm/min), 100% power and I have to make 4 passes to get it cut through. 3 passes would be enough sometimes but I have noticed that if there's clumps of glue in the veneer it need the 4th pass to cut though. I don't want to risk it so I cut the 1 extra pass to make sure I'm though.
Does this sound ok? I just feel like people can get though with 1 or 2 passes in the videos on youtube.
I am an Engineering student interested in doing physics demonstrations for fun. The first unit I want to cover is optics and I have everything I need except for lasers to show the direction of light though lenses, prisms, diffraction gratings, etc. I have a red laser diode from a DVD drive, a blue/violet laser diode from a blu-ray player, but I need at least two of the same wavelength so that I can demonstrate image formation. Are the cheap ebay lasers viable sources of laser diodes for my own circuits? I have watched a ton of videos about how dangerous they are, but I don't see why I can't just deliver less power to the laser diode to keep it below 5 mW.
Disclaimer: If I sound like an idiot, I have very little knowledge of electricity and circuits and will be taking E & M next semester. I won't actually create the circuits until I actually know what I am doing.
Hello everyone and happy new year,
I have a quick question as I would like to combine a laser helmet to my topical minoxidil + finasteride regime but I really donβt want to step into the 3600 dollars territory for a Capillus hat plus 3 years warranty as it really feels like a rip off.
Do you have any suggestions to potential cheaper alternatives with reputable tech?
In particular Iβm interested in the 272 diodes alternatives.
Many thanks in advance for your help!

I want to send a signal at a decent distance with aiming accuracy using an IR laser. I know lasers use drivers for consistent power, so the concept of using one to transmit a signal seems to go against this idea. Is this a possible feat to accomplish using inexpensive parts?
I was looking to purchase a laser engraver: the atom stack a5 pro 40w to be exact. It has an output power of around 5.5 - 6w. I would be using it solely to cut veneer up to a maximum of 1mm thick. Would this be possible without turning the veneer into a charred mess?
Hi everyone! I'm new in the laser world and want to maintain my eyes and the eyes of everyone around me. I'm currently using red laser diodes (these ones specifically https://www.amazon.com/HiLetgo-10pcs-650nm-Diode-Laser/dp/B071FT9HSV/ref=mp_s_a_1_3?crid=2X1QA5MCU88Y6&keywords=laser+diode&qid=1638932991&sprefix=laser+dio%2Caps%2C91&sr=8-3) with a fog machine to make a visual display. The lasers will be static and pointed away from people but I'm wondering if there are any issues with working with these besides having them directly pointed into your eyes. Can you stare at the beam itself (visible in the fog) from a couple feet away for prolonged periods? Is it okay to look at the diode itself when it isn't pointed directly into your eye? I'm running these on 2-4 AA batteries so the brightness varies a bit. Just want to be safe.

Brand: Ortur laser master 2 LU 1-4 LASER
Currently running my laser 18 hours a day to keep up with orders, will it die?
I'm making sure the fans on it are clean of dust to keep the temperature down, any thing else I can do?
Should I let it rest? haha
Cheers guys
How could i use this laser diode (module i guess), without burning it out continuously? Using a wall adapter. Also, anybody willing to help me with similar laser and circuit questions in pm/dc?
Hey, I have a 20W Neje diode laser that I want to mount on this kind of machine (below). The problem is that for diode laser, it seems to be useful to have a Z axis to be able to do multiple pass at multiple depth (like for cutting thin wood or cardboard). Do you think it can still be possible to cut without this Z axis ?

i found a 1550nm laser online is it true that that wavelength is eye-safe?
