High-power
lasers are used to
compress gas plasmas by radiation pressure.
The reflectivity of a plasma is unity if the
electron density is high enough. A
laser generating pulses of radiation of peak power 1.5
GW is focussed onto

Solution: Click For PDF Version It is given that the reflectivity of the plasma is unity. If the power of the laser is P the momentum transferred per second by the laser beam to the plasma will be
