Is it possible for a photodiode to sense a laser beam from a very short   
   distance when the laser beam is not directed, to the photodiode itself. The   
   photodiode is placed just 1 inch from the laser beam, perpendicular to the   
   laser beam in a dark room, so    
   will the scattering by the air be enough for the photodiode to sense that   
   laser? There are dust particles in the air, but not much.   
      
   Tech specs of laser are:- Max output <1mW Wavelength 532nm +_10 Class II laser
