The role of different factors favorable for the arrival 
of the liquid-drop phase of the target material at the erosion flame 
has been elucidated. The crushing of particles of the liquid-drop 
phase in the process of their motion toward the laser beam has been 
revealed. The conditions under which the liquid-drop phase influences 
a laser-radiation loss have been determined. The methods of control 
of the parameters of the liquid-drop phase in erosion plasma flames 
have been found.
