Oh baby! That is one of the sexiest beam shots I've seen in a while. Thanks.

I am have trouble starting a fire with mine. I focus it to the point where it just punches a hole through the magazine page so then I make the beam bigger but still no luck! What am I doing wrong?

Re: 1-1.2 watt 445nm lasers CHEAP $180

Got mine tonight and the thing is so bright I think I went deaf.:confused:

Deaf from all the screaming I did in shear excitement. Compared to the tight green beam of the 532nm, this puts off a gorgeous deep blue beam that is velvety soft. Very ethereal and something I just want to stare at forever. You rock yobresal!

As I stated in earlier posts, I'm only using this as a pointer at night and wonder without glasses, from the edge of the host, how far out is it safe to just look at the beam? Right now, I'm using the side of a mountain about a mile away to focus the beam to a dot. I want to look at the beam even just for a second but until I hear from you guys about this, I'm just looking at the beam through my peripheral vision while looking at the dot.

yobresal's lasers ignite paper pretty easily (when you have it focused properly). What i do is crumple up a piece of paper and focus it to a pinpoint and within a few seconds i get flame. Just keep trying it can take a few times to get a flame but these things are awesome and can definitely ignite paper.

Since everyone is lighting paper, matches and popping balloons I figured I would try something a little different! :D

Here's this laser setting fire to plastic!

YouTube - Burning plastic with 445nm diode laser producing flames!

How about lighting a sparkler?!

YouTube - the sparkler

Some fun with a thermometer!

YouTube - Raising the temperature! Pointing 1.2W+ 445nm laser on bulb of spirit thermometer!

Read the descriptions in the video for details. All videos are 1080P so click that option if your connection supports it for best viewing experience.

Be safe guys. I know we've heard it at least 1001 times but you have to be careful!

It's funny how you include the " cool down " time for the laser in the video.
Nice videos anyway

This is just typical use. You should give it a break every once in a while though. ;)

If the collimator ring is hot to touch that diode is running very warm. Nice thing with this much power is you don't NEED to have it running long to get a result!

I may do a video with breaking a thermometer. There's one on youtube with a lower power (1/2 watt maybe) 445 and it took surprisingly long for it to heat it and break the bulb. The longest I can hold it on there is perhaps 1-2 seconds before the liquid has completely filled the upper expansion area. Without a shield in front of the camera I'm not going to burst it for obvious reasons.

Is the crackling sound in the Thermometer video the liquid boiling?

My Yob 445 arrived yesterday. Did a quick outdoor function test (oooooooh bluuuuue!) and read the 445 eye safety thread. Then pulled the batteries out to wait on any further testing until my goggles arrive...
