Is this an example of an Airy Disk?

I discovered that when I burn through a CD case with my 300mW green laser, the following effect is produced on the wall:

At first, I didn't know what this was caused by, but I found this on Google:

Is this what I'm seeing? Or am I totally wrong?

Yes. You can compute the wavelength of your laser from the distance of the pattern from the aperture, the diameter of the aperture, and the spacing of the rings. Have fun  

EDIT: "Yes" means "yes you're right"...

Jwc;

It also looks just like the pattern you get with a BluRay,
when you use one of the "objective lenses' from the original sled.

I guessed that it was some type of circular diffraction.
