The general optical transformation theory is used for the design for converting Gaussian laser beam into a uniform profile. The transformation system can be achieved with two phase-only masks system. The phase-only mask may be fabricated with reactive ion-etching on a quartz plate. Experimenra) results indicate that the output beam profile is consistent with the theoretical calculation. The conversion efficiency is higher than 95%.
