Abstract :
A pattern formation of the laser beam with polarization control was demonstrated by UV written patterning of the liquid crystal cell that had high laser damage threshold over 10 J/cm2 at 1 to 0.5 micron in wavelength and 1 ns pulse duration. The serrated soft aperture was fabricated by this procedure. A new kinoform plate is proposed for an application of the distributed phase plate as a beam focus control in the laser fusion experiment.
