What it is
A 2-minute EMPossible tutorial showing how to render from Blender with a perfectly white (or any solid color) background. It walks through the render and compositing settings needed to avoid the grey or off-white result you get by default.

One of other settings that can mess your transparent background is something in Composing tab. What I did was set perfect white color there with this tutorial: [this video] And then browse half of the internet, figure out to find the tutorial how I set perfect white background, and than discover I have to remove the middle box from Composing tab. To future me: I got that covered

The above answer is way more complicated than it needs to be, just use compositing.

I made a cylinder to hold a Gaussian beam. The intensity is calculated by the equation of the Gaussian beam. And the material is set like this (I make every choosable color to #FF0000): [LINK] The max value of the Intensity output is I0, and the min value is 0. Inside the Node Group is a calculation of Gaussian beam intensity distribution: [LINK] In the viewport, it looks like this(I used a transparent background): [LINK] After Rendering, it look like this(I use Cycles, and I make a white background in Compositing): [LINK] It looks dark, not that red, especially in the surrounding. I don't want a strong intensity, the red in the middle of the beam is fine, but I hope the color should be ligh
