[Laser] Interesting Question.

[Andrew T. Flowers, K0SM]

What do you mean by "something"?  Are you looking at a constant 
frequency? Broadband noise? I assume you are using a baseband receiver.  
I use this range for my DSP stuff mostly because it is relatively 
clear--it's generally too high for "natural modulation" (twinkling 
stars, etc), but I can imagine some phenomena that would put energy in 
that band.
