how to make a white laser

[andy_con]

colour ratio's

red is 4:1 with green
blue is 2:1 with green

so 100mw green would need at least 400mw of red and 200mw of blue

5mw green
10 blu
40 red

how long is the group buy on for

Is there any fixed ratio for white?
Therefore I can see different ratios used in different white lasers from companies.

Like 1 green , 2 red, 2 blue :-? :-/

depends if you use a 635nm red or 650nm red or 660nm red

there really isnt set figures, the only way for perfect white is analogue modulation

i will(in a long time) when i have every thing make it with 3 pots

 

[andy_con]

heres my white

 

[jamilm9]

thats i i think I'm in love :-[ [smiley=2vrolijk_08.gif]

I think mostly 635nm. What analogue modulation does? Adjust the output powers of 3 (RGB) lasers? :-?

BTW your white looks nice

 

[andy_con]

yes means you can adjust the power of the laser brightness so you can get a perfect colour match

yeah when i have mine i will just have 3 pots
