Ivan Khomenko shares some of the best techniques for creating laser textures

Step 1: Lasers I
Now I'll describe my way of creating a laser effect in Photoshop Extended.
After you load Photoshop you should create a new file which should be about 2000x1400 pixels. To make the lasers look more dramatic, I think we need to put them on a dark background - this way the effect from the Color Dodge layer will be more noticeable (I'll explain about the Color Dodge layer a little later on). So by using the Paint Bucket Tool (‘G' on your keyboard), you should fill the whole image with a black color.

Step 2: Lasers II
The next thing you need to do is to load the brush set attached to this tutorial.
Go to Windows > Brush Preset, then down at the bottom click on Brush Preset Manager and click Load. After that you should find the file containing the brushes and click done. When this is done, you'll find a lot of different brushes in the Brush Preset panel, but you can ignore them for the most part because we'll only be using couple of them. I've never actually used half of them, but it's very interesting to try some of them out in different situations. For example, if you need to create an interesting rock texture you could try out different combinations of brushes.

Step 3: Lasers III
So after you load the brushes you'll need to choose the second one from the top. Create a new layer by clicking on the Create New Layer button, and then draw three white crooked lines on this new layer.

Step 4: Lasers IV
Then you need to create one more layer and change the blending mode to Color Dodge. You can then choose any color you want for your laser, (it should be bright color though). I choose bright blue.

Step 5: Lasers V
Finally, you just need to paint your laser beams with a simple air brush on top of the white lines. So now with this very simple step, you have created blue lasers.
