Looking for a 450 nm laser at least 1w

I already explained that to you in post #28 and it's in the video I linked to in the same post.

Yes after another read i managed to find out were it goes.
Its all build and working :)
Good thing i have goggles, its so bright i can see the light around the glasses lighting up my room, but only see s tiny orange spot as the goggles blocks most of it out.


The beam isn't perfect, there is a bit of splash even as close as i can to focusing it to a point.

Good job. Be sure not to set anything on fire by accident.

Hahaha, ill try not to...
I want to see this thing at night!

I can feel the heat on the stainless steel body, and I'm only using 10 seconds at a time.

Whats the duty cycle on this?

You shouldn't feel any heat after only 10 seconds. I would have expected 30 seconds to feel it getting warm, that worries me a little. I would have thought 45 seconds duty cycle, but not if it's warm after 10 seconds.

When i say heat i mean i can feel a difference between temperature in the head and the tail. Nothing like i can't touch hot.

It should get warm but not very warm. It must never get hot to the touch or it will kill the diode. When the host is warm the heat sink is warmer and the module is very warm and the diode is getting hot.

The laser I have in that host is about 3W and 35 seconds is safe, yours should be around 2W so the duty cycle should be at least as long or more, but you could have an inefficient diode that puts out more heat, this is always possible.

I hope thats not what mine is like :(
Too bad I don't have a way to measure the output.
 
When viewing the beam without glasses it should be easily visible even in a room with a light or two on. Try burning a white piece of paper up close (with glasses on), be careful it may set it in flames. White is the most difficult color to burn. Be sure your batteries are fully charged first.

Its night here now. And it lite my whole room. Tried outside and WOOOW, its a light saber!!! its insane. Definitely can see a beam thats incredible.
I might have been wrong. I did a few tests for like 30 seconds, and the head was just slightly warmer than the rest of the body. I think its fine.
Ill see if i can post the pictures.
 
That's good news, I look forward to seeing pictures. I see you are in or next to a major city, considering that your laser isn't quite legal there, be careful not to draw attention to yourself if using it outside.

Here are the photos

In my room during day




At night inside room





Outside

 
Just did the electrical insulation tape test. It cut all the way through in less than 2 seconds.
Tried a silver one and it just caught on fire.

Also did the candle lighting, that took a while until it lit. About 10 seconds.

How much can we rely on these eagle goggles from the 450nm light hitting our eyes. Just curious for my safety. I think this is one of the best investments in lasers and I'm glad I did so. I went for the 190-540 & 900-1700nm.

Great pictures. Those glasses should protect you when viewing the dot of a laser up to 10W, but if taking a direct hit I don't know, I would think a couple of seconds or maybe even several seconds at up to 3.5W. I don't think anyone here did any proper destructive testing of those glasses, but I am sure I remember two people doing some testing on two of the Eagle Pair. I remember someone had a laser roll off a table and flash across his eyes and they protected him, I think the laser was over 3W, it was a very long time ago so I don't know what thread that was or I would link to it. I also recommend owning some tripods to hold your lasers. You can see my tripods here: http://laserpointerforums.com/f44/targus-tripod-88257.html
These aren't just for convenience but also for safety, always use both hands when using your laser or put it in a tripod and then take your photo or whatever your going to do. I once had one slip out of my hand when trying to take a photo with my other hand, someone else here did too, and the one that rolled off a table. These things are of course more likely to happen when you're not wearing safety glasses.

I have a small tripod, just need to find some sort of attachment that can hold the laser and attach to the tripod.
BY THE WAY the photos were taken with just a Samsung S5, nothing special.


I did a solder melting test, and it worked really well. Very fast, was surprised.
 
Is it bad to point the laser at a wall about 2 meters away and look and or without the glasses? Does it damage your eyes in any way, considering it's and white wall and there is no beam refeito to the eyes.
