I am searching for a USB powered laser pointer (power should be more than 100mW but should not pass 500mW) All of the lasers are either off-sale, expensive or rare. Best Website to find one ?

Hi,

After reading some studies I'm very interested in laser therapy for my dog. My vet doesn't offer this. It seems I need a 980nm laser with at around 6W of power.

Everything online is thousands of dollars. It ranges all the way from $3500 to $25,000. Am I missing a potential vendor? Maybe a different machine that doesn't have all these automated functions for medical use?

Thanks

I bought a 5W laser a few months ago. It seems ebay finally caught on.

I've been brainstorming ideas for a multitool phone case. And I want to put a laser pointer in it without it being too thick.

If anyone has any ideas of things I could add, I could probably try to add it.

I'm researching into the laser classes and can't seem to find a good answer on this. I'm wondering if my laser falls into the 3B class or 3R class.

I have a laser, which has a peak power 100mW.
But it is on only 10ms at Hz. So each second it is on for 50ms total.

This gives me an average power of:
100 * 50/ 1000 = 5mW
A 5mW laser would fall into the 3R class.

Reasons why I'm wondering if this is possible is the Intel Realsense D435.
This device has a 360mW IR Laser / Random Dot projector, but still is only a class 1 laser product.

I want to create a similiar device with a laser that creates a dot pattern (not random) but am wondering how they got it classified as a class 1.

Hello, I want to build a laser pointer from scratch, but I’m not sure how to do it. (I remember I had one similar to the one in the picture, and I burned it). What does each of the pins do? How do I attach the lens so that it produces a straight point? I also saw that people use a driver (which one should I buy, preferably on AliExpress, or how do I make one?). I have experience in electronics, and I’d like to learn more about lasers.

Hey, I'm looking in the mirror and seeing how the laser reflects. I was surprised to see that if you arrange the laser dots, it will shine perfectly in your eyes and I was exposed for half a second or less. And almost immediately, there was a blind spot in the center of my focus. The blind spot is not black, but I can't see the detailed image it's too blurry in that dot, can it recover?

1000mW blue laser beam Help me Guys 🥲

Hello laser enthusiasts. I have ordered 9 mm powell lenses and need a 532 nm laser diode with 1 w + power output, preferrably with housing which fits the lense. Any advice?

Total beginner here.

I want to prototype a Michelson Interferometer with VCSELs. Can anyone recommend a business that could cheaply fabricate that?

It needs to be with VCSELs (class I or II) and low power supply so that I don’t blind myself. I also don’t want to play around with soldering. Safety first!

is it typical to see the 1064nm IR light a green laser puts out? i know human eyes can see past 700nm even though that's when IR starts, but is it normal to see that far out? in other words, are my eyes special? the light was very dim, looked dimmer than a dollar store cat laser. even though that green one is 50mw.

I recently bought one of those green pen lasers from my friend, who bought it in Paris. I however have no idea how much Mw it could be, and i could not give an estimation whatsoever. I did find a nearly identical looking one in a video, where they said it was 87 and 96 Mw. I also found a completely identical looking one online, but it doen't say how powerfull it is.

Spent a few days scavenging the shed out back for parts/inspiration haha. It has a 4w engraving laser module in the front portion. You can see the fan in front of the "fusion core". The area holding the "fusion core" is hollow and you can see right through to the other side. The LEDs for it have a separate circuit and battery so I can leave the light on and use it as a display piece while the laser battery charges. The battery pack attached to the base of the grip is removable and has a tensioned clip to hold it in place as well. The battery is from a 12v hyper shot drill that I got it at Walmart. It has a DC charging port directly on the battery itself, which is nice. The telescopic magnet on the front acts as a focal point range finder. I only use it when wearing appropriate eyewear, and since I can't see the beam/focal point through the glasses, it's hard to determine where the ideal burning point is immediately. I adjusted the original lens so it can be focused for a long beam or up close for light cutting applications. I'm unsure of what I'd name this blaster.

Hello, everyone! I'm very new to lasers and don't have much of a foundation when it comes to understanding the basics for someone wanting to get into the hobby/collection of quality laser equipment.

For Christmas this year I was hoping to buy a laser for my brother (who is very smart and loves everything related to science) that is accurate to its description and from a reliable seller.

If I wanted to buy a laser that is visible in the air and would get considered a good price-to-quality ratio, where could I get that from? And what kind of goggles could I get him that would provide the necessary protection?

I was just curious about laser safety at astronomical places, from what I recall some observatories use several ~30W lasers that they shine into the sky. At that kind of power levels is there a danger from reflections off of dust? Is there a power level where reflections off dust or clouds or something starts to become dangerous? What about when the starlink satellites use laser communication, if one of those got pointed at earth would that pose a danger to eyes?

I bought a green laser pointer and tested it in my house. It's pretty damn bright, being able to pretty much turn my bedroom green however, I am kinda getting bored and want to test it on something more interesting - like a wall in the distance or an apartment in the distance, of course avoiding windows and focusing to solid things. Will I get in trouble even if no harm is caused?

Hi, this is my first post here!

Does anyone know how to remove the diode/driver from a sanwu Striker module? I have a blue 7w that’s broken and want to check it out. Thanks 👍

so i just bought this laser (from online) and I'm a bit confused about its safety rating. it says max output power is less than 5000mW (which implies that its near that) but it also says its a class III laser and this info is kinda conflicting with each other based on the laser safety chart here: https://www.lasersafetyfacts.com/laserclasses.html also note that i can hold it on my skin for a while and i don't feel anything. its also a usb charging one so no batteries are needed. its just a cheap Chinese one, based on the fact that the box was covered in weird grammar issues from the translation process. could some1 please help me here lol.

500mW for 30€ sounds too good to be true

I built a 2 axis audio driven laser galvanometer and would love to capture audio waveforms/lissajous patterns on photo paper, but I only have a laser that emits in the 650 nm range, which dark room paper is of course not sensitive to. I’m wondering if anyone could recommend a market place/link to an affordable laser that emits within the 540nm range or even 400-550nm range. Searching on Amazon leads to vagueness of the emission spectrum and I don’t want to gamble on cheap stuff that may or may not work.

He was shinning the laser near me and it hit my eyes I didn’t feel anything right away but when I went home I couldn’t really read anything dark. It’s like I’m seeing a flashy light. I’m not sure if this is in my head but today while I’m at work on my computer. The white is flashing black a little bit.

I’m hoping it will heal or should I hit to the doctor.

i recently found out that new 303 are way more powerful they were because now instead of old dpss laser diode 532 nm now they use 520 dirct diode laser this could be false these are according my new green 303 s

but with new direct didode, you can from 250 mw to over 1 w thats crazy and incredibly powerful green laser are always tends to be dangerous now they are even more dangerous you should really seriously care about the safety. at least now they don't leak IR i have some burning test of 1w laser i think but always please be care with high powered lasers

Hi! Where can I find laser safety glasses for Class 4 Fiber laser with a wavelength of 1060nm and optical density 5+
