[Laser] Lasers vs LEDs & ARRL contests

Hi guys,
why to limit optical sourceys anyway?

Limits prevent the freedom experimenting with any optical sources available.

Optical pollution is present every day when the sun shines and when  
artificial light is switched on during the night.
The beam angle is to be limited for technical reasons itself because  
no sufficient signal level will hit the optical detector when the  
angle at the transmitter site is too great.
So I think no additional regulation is required.
What is the advantage to limit the bandwidht?
You can use white LEDs for example for transmitting broadband signals  
like TV or similar with usable efficiency.
You will exclude that if you limit the optical bandwidth.

My opinion is, bandwidth and output regulations make sens for radio  
applications, not for optical experiments.
I am sitting here in Germany where the optical frequency range may be  
used by everyone without any regulations (exept safety precautions  
using powerful lasers).
Why should radio amateurs work under worse conditions than someone  
without amateur radio license?

I think the last thing we need is to limit anything in optical amateur  
radio regardless where in the world amateur radio takes place...
