Unlike in a CRT, the phosphor will be fluorescing when stimulated by the 
laser.  In a traditional CRT light is principally generated by 
phosphorescence, a process whose "off" stage follows a Poisson 
distribution (which someone who's set up a CRT based telecine will know 
as afterglow).

Fluorescing is a _much_ faster process, so the response time will be 
very fast.  That said, without help from a little afterglow they'll need 
to scan that laser pretty fast to make sure the picture doesn't flicker.
