What is the percentage of laser that is scattered by the plasma?
It is very important, because if laser can go through the plasma, also plasma radiation, so plasma would radiate so quick that it would be impossible to heat it up:
Pemit=area*C*T^4
C=emision coefficient
If area=1m2 and temperature is 20keV (20000*11600 ºK),
Pemit=C*2.9e33 watts (Sun power is 1e24)
I think plasma area must be very very little in order to reduce plasma emission
