Step 1 - Make new file (my is 400¡Á400px), choose dark canvas color, thus we can see the light rays better.
Step 2 - Place your logo at the center of canvas (Tip: you can use "Align" panel for that)
Step 3 - Clone object / Edit » Clone or Ctrl+Shift+D
Step 4 - In Properties Panel » Go to Effects » Noise » Add Noise ¡ with following settings: Amount=400; Color - unchecked
Step 5 - Add Blur » Gaussian Blur: Blur Radius = 2.3
Step 6 - Add Adjust Color » Brightness/Contrast: Brightness = 24; Contrast = 96
Step 7 - Add Blur » Zoom Blur ¡: Amount=100; Quality=100;
!NOTE! This is very CPU intensive effect. You may want to turn-off preview checkbox on bigger images.
Step 8 - Scale Object with pressing Alt key (for transformation from center of the object) 
Step 9 - Change Blend mode to "Screen" and Send Backswords Ctrl+PageDn
Step 10 - Now you can make color of the logo darker and put some white "Glow" live effect
Step 11 (Optional) - To further enhance effect you can check color in the "Noise" live effect

Or use comments below! English is not my native language! I hope you point me to any errors I have.
P. S.: download command that do almost all of this tutorial for you here. Put jsf file in FW commands directory. It is not very well tested, so use it at your own risk
