A simple optical device for generating square flat-top intensity irradiation from a gaussian laser beam

Abstract A simple optical device, by which a square flat-top intensity irradiation area can be produced from a laser beam having a gaussian profile, is developed. Calculated nonuniformity [( I max - I min )/( I max + I min )×100] and the efficiency of this optical device (total energy irradiated in the square region/total energy of the gaussian beam) were 3% and 94%, respectively, for the best irradiation condition.
