portable RGB laser less then 50mW
 
Hey everybody thanks for interesting in my first thread i actually want to build a RGV 7 color portable laser it works with 3x 9V batteries I'he already tested everything in theory ,but i need some help in the laser System itself it should work with : 10mW 532nm , 13mW 635nm and 20mW 405nm is that correct i want to be finished with his project april 2013 so there is not a lot of Time to make it so please help me however you can I Know every important thing about lasers so i don't see a problem in building it with help of this forum i will Post Photos of the assembly of this for me amazing laser do you have any tips for me ? Then Post them please !! Thanks again to everybody who is helping me here .

Have you seen this thread? It would save you some time, hassle, and maybe even some money

It's also save me some time and hassle if your post had a bit of punctuation in it, I almost winded myself trying to read that.

^Ha can you imagine if someone actually talked to you like that? A non-stop runon sentence on a single breath of air

I Don't want to buy a full module. I want to DiY ! Even when its just 140$ and i don't the waste of the three lasers ,its just white . I need a 7c that i can switch how i want . All lasers that i want to use don't need cooling . I will draw what i want on a sheet of paper and post that here .
@Things Sry but i was really nervous what i should write to don't be ignored and/or called unfriendly for my first post do you understand ? Thanks for fast reply :)

Search up white fusion. It's a very portable RGB laser.

It is not just white there are potentometers for each color. Also I believe there are clips to attach switches for each color.

Still i want it compact it should running on batteries. And are my laser outputs correct ? I mean 10mW 532nm and 13mW 635nm and 20mW 405nm sounds a bit like its not correct ,someone can help ?

This will help you in determining relative brightness of different wavelengths

I'd kick the 405nm up to 50mW or so. It's REALLY dim compared to the others. Maybe consider a 445nm single mode diode since they're relatively low power, but produce a better blue.

Re: portable RGB laser less then 50mW
 
I was thinking to use 445nm or even 473nm but 473nm was to complicate and to large to use in a that kind small housing . To the 445nm i didn't found any low power single mode :( so i will use a 50mW 405nm.

Re: portable RGB laser less then 50mW
 
The rated power is just the maximum power you know. You can always reduce the current to reduce the power, and those single-mode 450nm diodes have very low threshold currents/power.

Well i Know much about lasers you don't have to tell me that :) tomorrow i will upload a not correct picture of the circuit tust i want to use and after that a correct circuit for our Pro's here
:) again thanks a lot for this fast reply

Re: portable RGB laser less then 50mW
 
And i don't want to use 3.8mm diodes i want to use my own housings they are for 5.6mm diodes maybe later i will make a new housing and buy a 50-80mW single mode 450nm for the same project but first i really want to make experience with 405nm i never had a 405nm one over 1mW...

If so then, why? :thinking:

Its not correct cause not the right symbols for nearly everything was used
