Looking for a laser thats bright enough for daylight but won't melt plastic. Also needs to be able to plug in and stay lit 24/7. Any recommendations?

I want to use a bunch of laser diodes that have their anode connected to the casing with a driver that supplies operating voltage to the anode. However, the diode needs cooling and having the operating voltage on the cooling block is not optimal.

Do any of you know a thermally conducting but electrically isolating material, I could use for this purpose :)?

Two workers came to my room today to install the air conditioner. When they came into the room, one of the workers took the laser rangefinder without any warning and started using it, accidentally shining it in my eyes. Now I have a headache, and my eyes feel uncomfortable. I've Googled about concerns regarding whether laser rangefinders are safe for the eyes, and the answer is that they might cause some damage. Does anybody here have any experience to share? I’d appreciate it because now I just don't know if I should be worried and go see a doctor, or if I'm just overthinking.

Looking to get a powerful sanwu laser and safety googles, to play around with. Wondering which one to avoid. Ofc i'd always have safety glasses but JUST IN CASE i hear some are even more dangerous cause it doesn't trigger blink reflex? People said green but also blue?

I'm looking for a driver for a 35V 4A laser diode with PWM for a display laser. I'm having trouble finding off the shelf parts for this. Any suggestions before I start designing my own?

I am looking for a cheaper alternative to the 500$ agriculture anti bird lasers. I'm not a big farm and hand held is fine. I've read green is the best color (bandwidth ) but no idea about the rest. I need some good range and I know daytime is hard but but yea. Me vs these few birds is a daytime thing. 60 to 100 is my budget. Sanwu has some green pocket options but I'm confused by things like DPSS, mw etc. All I really know is green is best

525 green 120mw for 150 530 green 30mW fixed focusable

They also have some sort of expander thing I'm wonder does that make the beam wider at the other end and would it be helpful Distance up to 14mike but realize that coukd not be possble Other manufacturers and recommends welcome

PS I'm a hard core animal lover bird watcher environmentalist. Absolute zero intention to hurt anything. Just hoping to discourage a few specific birds from not hanging around here with brief flashes

I'm looking to build a laser lamp that moves with music. Sort of like the old school laser light shows.

Something similar to this maybe. https://youtu.be/xIZKDxmlEjE?si=Dhqs6RHtI2cr5yuV

I'm considering making a few and then filtering the speakers to different frequencies.

Any tips or suggestions?

I am talking to this manufacturer to make a laser for my company. It’s supposed to be a low power laser that general consumers can operate without having to pay $500 for software and stuff. I have 12 pre-programmed buttons on the back that will each make a different laser effect. How do I tell them what each button does? Send them a DMX file or something? Please help

Can anyone tell me information about this unit? Make? Wattage? Safety? This was pointed directly at a dance floor and right into the eyes of guests. It also destroyed 5 cameras and I may seek legal action, but I need to know more about this thing....

Thank You.

So basically, I turned on my laser with >5mW, class 3a, on my window, and the reflection got in my eyes. My vision feels kinda weird now and im worried.

There are 3 capacitors in the first stage of the voltage multiplier, they are 500V 10uF. One is pushing it's 'cork' out, I think this is why it is not starting now. I tried Mouser, I tried DigiKey, both have super long lead times for these.

Does anybody have a place to buy aluminum electrolytic 500V 10uF radial lead capacitors?

Finally designed a pcb and sent it to the fab house, the finished design supports input voltage from 7-30V, and can drive loads with forward voltages up to the supply voltage and current up to 3A. It supports full analog modulation with a 0 to 5V signal, or can be used with TTL. Also has an offset control to adjust the 0V modulation signal to be just before the laser diodes lazing threshold, for a near perfect linear relationship between output power and the modulation signal.

I bought this laser off of Amazon: https://amzn.in/d/2rF39CC

And it simply says that it’s a class 3 laser product. I don’t know what safety precautions to take for this. It claims it’s <5000mW but that seems like a very high upper bound.

Specifically I wanted to know if it’s fine to look at the point of reflection when it’s reflected off of marble / a mirror at an angle. My room has lots of mirrors and marble so I don’t want myself or my dog to be blinded by mistake while playing with this laser. Thanks.

Just ordered my first laser from jlasers and I’m very excited about it but was just wondering on how long it usually takes to get delivered from the day of purchase. Just curious to hear from those who’ve ordered from them before.

I constantly see a blue dot in my vision no matter where I look I only see it when it's dark could this have happened from a blue laser being pointed into my eye? I've never owned one my self but I know ppl that have them

Hi all, I bought a laser pointer : https:// www . amazon. it/Manybuy-Puntatore-Tactical-Carabina-Compressa/dp/B0BGH6BWT5

When I put batteries in it, it powered on without the end cap because the last LR44 touched the negative contact , I didn't thought about this issue when inserting batteries. It was directed towards a matte paper table surface, but there was a plastic transparent empty bag and a transparent plastic package with spare batteries, so partially reflective (even if not like a mirror) and not far from my eyes...
I did notice the dot when looking at the table surface, but I didn't immediately thought at the issues with reflections...

I never looked directly at the beam, I didn't see flashes or glares, didn't felt blinded, right now my sight seems fine, trying looking at a white wall or at the Amsler grid I didn't notice issues and already more than 3 hours are passed.

I'm mainly worried because when I checked this laser was labeled <1mW on the device, but Class 3A 5mW on the website, so there's something wrong with this and I just think it's one of those "wrongly labeled" lasers, maybe higher than 5mW ... Even if it's powered with 3xLR44 so it definitely cannot have a very high power it's worrying me anyway.

To have an eye damage with a visible laser, you always need to have felt "blinded" or "flashed" ? Or you may just have had the laser in your eyes damaging them and not feel it?

Thank you

Hi All, I’m trying to find some Ti:Sapphire for a non-laser project and I thought I would see if anyone has an old rod/window/other part sitting in a box somewhere. Does not need to be laser-quality anymore, we’re not trying to make a beam. eBay is completely empty and the only other options are new sapphires which is more expensive than I need for what I’m trying to do. Thanks!

Absolutely no weaker, and preferably not a lot stronger. Any product suggestions? Also places to buy welcome, it's really hard to find proper specifications on most sites

hey im thinking about starting off with high powered lasers bub i dont know where to start any suggestions?

I salvaged this module from an optical drive, however it seems to have 3 diodes?? Or are there 2 diodes and something else?
