3W 445 + 1W 532=white WHY?

The dichroic mirrors only reflect 90-something percent of the light. The remainder is either absorbed, or transmitted. You see the transmitted beam.
 





Wow.. that looks pretty good :)

I see you're combining 2 445's there - what does the spot look like at a distance?
 
It may not actually be the eye overloading, there is another plausible explanation.

I've observed it with the Arctic and a 250mW greenie before, it's similar, instead of blending to produce a turquoise/cyan, the blend appears to be a very off-white colour.

It can't be overloading of the eyeballs because both the spot and the beam itself appear to be a very bluish white.

It's far from a pure, neutral white, but nonetheless it is 'white' enough to be classified as a cool white.

Are looking at the combined spot without safety glasses?? If you are, your eyes are just being oversaturated and protecting themselves by giving you the impression that you are seeing "white". You are looking at laser with a total of 4W.

Be careful, you may be damaging your eyes.

Take care of them.

+rep for that excellant advice- I have heard that about all 405 too. Our eyes apparently do not adjust(un-dialate) like they should and too much, even just off a white wall, can be harmful. I always say if you are seeing a lot of after-images they you need to step away or put on the protection.
 
This looks amazing! I love the cyan color beam. I think Cyan is my favorite color. Currently I'm working on a Yellow beam (Red/Green combined beam) laser. Once I finish with that I will work on the Cyan color. I really like yours! Good job.

It may have been better to PM the builder to tell him 'good job'.

We look fwd to your new thread when you get your combined lasers done...

Yes it does seem white..
Best part is that I change my palette on the software to get rid of the very common 532 green. I added some blue to get what I think is very close to the Argon 514 green. My favourite laser colour. I've spend the past half hour staring at the green beam.

The picture does not quite do justice for the actual colour...but it's not far off..

I love the picture of your dog in the background. :) I'm a big dog fan.

I also love the 514nm green myself. I think I will play around with blues and greens and see what color combinations I can come up with. I love cyan and the light green of the argons.
 
I have a question about your build... what mixture of 445nm and 532nm are you using to get your Cyan and light green color? Is the 3W 445nm + 1W 532nm your Cyan build? And how would I modify it for the green? Maybe go 1W 445nm +1W 532nm? Can't wait to start with this one.
