I'm back

Yo bro, I am in China now :D it's been awhile since I posted.

Beijing, China!

Thanks for the advice, Pi R Squared. I'll change my location soon. I am in Beijing, China. I have already visited most of the tour able sites around here.CNI sounds interesting... Anything else I could take advantage of in China, mainly regarding lasers? Why the garlic... Is there anything...

Once upon a time... I posted a thread that I was going to China and how this might impact my laser hobby. Now I am here and at the request of a user in my first post, I made this second post. Any follow-up comments or suggestions on what to do in China? I noticed that certain things don't...

Well, it seems that a brown laser is really a dull orange laser :P

@BowtieGuy Umm, that's just a for fun poll...:) @Cyparagon So you are saying that though the color brown is made from red and green, brown light is made from...dark orange?

Hi guys, it's been a while. So, I've been thinking about this very interesting question. Something that intrigues me a lot is the fact that red light and green light blended make yellow light, but the color red and the color green blended make...BROWN! So, is it possible to make a brown laser...

Yes, Cyp, I know that infrared is invisible. I am just wondering why you can dichro visible colors, but suddenly when you go into longer wavelengths you suddenly can't do it! Where's the line?!

:thanks:

Good idea. But I am an 0ptics n00b t00 :(

Hi guys! I was thinking about making a monster red laser, and 'monster' means combining lots and lots of diodes (in my imagination anyways ;) ), so I was thinking whether I could dichro two different hues of red into one beam of medium red. Suddenly I realized there was such a thing as infrared...

All in all, does that mean that it combines the beams? Or does it merely 'lay' them side by side?

Wait.... are you trying to combine beams? I don't really know about this, so please correct me if I'm wrong.

Sweet!

Homemade goggles?

Wow thanks everybody! Yea, scouring DTR's site, he seems to have some CHEAP 700 mW reds. I might knife edge 'em, though I've never done it before and I hope i won't mess anything up.:yabbem: io heard knife edgoing increases the beam diameter..right?

Goggles check?

Hi guys! Long time no see. So researchin' around, I found out that someone had made a 7.3 W Blu and that is just awesome. It appears to me that 2W seems the threshold for green, but I don't really know about the other colors. Red? Yellow? Purple? Infrared? And what might be the highest possible...
