One of Rick Trent's 3W hitting the clouds. Weather station said 6 mi visibility for this area.

I did the same thing last night.. They were some stratus and altostratus .. (2-4km) Absolutely beautiful.. And amazing! Thanks Antharak!
 
I was hitting the clouds with my 1W 638 build RHD made me. The 1W reds are so intense with the rain and fog. It was awesome, sorry I didn't take any pics.
 
Can you take some beamshots in the night of your 1W 638nm for me? :)
 
I live immediately below Class B airspace or I would do something like this... looks awesome! Thanks for sharing the pics!

Our place has a fair amount of aircraft traffic. I just be careful where i am shining it. Dad thinks they can see a super bright beam but i did an experiment and if you look at the laser side on and go back a few meters, the beam drops in brightness significantly. So i can imagine it wouldn't be visible from kilometers away, unless it was shined directly at you.

I shall see what I can do tonight. Looks like its gonna rain again sucks that its dropping from 75 to 40 though.

I'm out in the woods, I own the sky lol.

Thanks, i am going to do a build with a 500mW 638nm mitsu and i was wondering if i should run it at 850mA which would be about 500mW and change the wavelength to about 645nm or push it at 1.25A which will put out about 700mW IIRC and then it will be about 655nm i think (these ratings are with a 3 element lens). Is it noticeably different in colour to an lpc? What lens is in yours as well, a G2? Sorry for all the questions :o

Mine uses a G1-650 lens from Jayrob and I believe its around 1.2A. Hits just over 1W.

There is a HUGE difference between my 650nm 1W and my 638nm 1W, the wavelength shift is not that extreme with the 500mw diodes, it will probably be around 640nm at 1w, and it will still be WAY brighter than a 1W 650nm.

The difference actually astounds me, as these wavelengths aren't really far apart at all. Its hard to believe the difference in brightness.
 
Very cool pictures.
As as for what Laik was asking, the Mitsubishi diode is nice an powerful but just remember the laser dot is not a dot but a line. With the g2 lens you get the power but the line is just awful, if you use a 3 element the power goes down drastically but you do get a better shaped beam.
 
I could get a LFL lens to still have that high power and have an alright beam.
 
I think its kinda awesome with the G1, its like a crazy red ribbon in the sky, and when viewed from the other axis, its a thin red line that is crazy bright, just depends how you look at it.

I have a 3 Element on my 500mw 638, and while the beam is much narrower, the amount of splash is absolutely insane. Plus your losing a ton of power, and creating more heat around your diode, from all that back-splashed laser light that cant fit through the lens.



Both have their benefits and their problems.

You really gotta try all the lenses with these reds to see what pleases your eye the most.
