Fundamental studies on the power transmission by laser beam have been done. Experimental resultsabout a plasma direct converter (PDC) from laser energy to electricity are reported.
It is found that laser-produced plasma is far from the perfect ionized plasma. Using a 5m-long chamber, electrostatic separation of ions and electrons in the PDC has been done almost completely, and the conversion efficiency of the PDC η3 has been improved using a venetian-blind collector. And it is found that the conversion efficiency from laser energy to plasma η1 is increased and the maximum conversion efficiency η3max is decreasedwith increasing laser energy.
