what do you mean by gamma laser?

just heat the filter and it changes the color of itself and the color of the photons

R = red filter
B = blue filter
O = empty space
P = purple photons
C = clone
W = white photons

C W W R O O O P P P P P P P P P
C W W O O O B P P P P P P P P P
C W W R O O O P P P P P P P P P
C W W O O O B P P P P P P P P P
C W W R O O O P P P P P P P P P

Best explanation I can come up with :/

It is a makes purple, but it doesn't work that well.

I'm got it!
I'm edit my Beam Laser To Gamma Beam laser.
Check my saves. ;)

As the maker of the original gamma ray laser, I will tell you how I did it... XD
Instructions:
- Use PCLN as the Photon Emitter
- Put the PCLN pixels in rows (however many you want in a row), with black hole in between
- Put Filter in front of each row, at least 3 spaces of dead space in between the PCLN & Filter
- Make the rows of Filters 2-3 pixels long and spaced 1 pixel apart
- Make sure that the Filter is not touching anything, especially the other rows of Filter
- Heat/Cool the PCLN to make a certain color...

*Note different amounts of different colors of filter can make different tints and shades. For a true purple laser, use 2 blues and then 1 red and then 2 blues and then 1 red and then 2 blues: If you use red/blue/red/blue/etc. you will get a more pinkish color.

Here is my (the original :D) gamma ray laser:


You are using a technique to place 2 lasers on top of each other, one red and one blue, but if you use two lasers next to each other, then you can make a darker shade, making it less of a pink and more of a purple. But still, +1 for figuring it out yourself :)

Good luck making lasers! Hope this helped! XD

P.S. Thx for noticing my gamma ray idea, I never thought it would catch on.
