Error Reduction Algorithm for the Generation of a Kinoform with Laser Diode Array

In recent years, technologies related to laser has been advances, processing technology using the laser has been used in a variety of situations. In this case, the laser diode is superior to other lasers in luminous efficacy. But the power of laser diode is lower. So we use a laser diode array module to obtain the necessary power for laser processing. In addition, shaping the wavefront of the lasers is ideal in the laser processing. In this paper, we describe error reduction algorithm for the Generation of a Kinoform with Laser Diode Array. Kinoform which is a phase type Computer-generated hologram that does not modulate the amplitude of the light, the utilization efficiency of the light can be improved. Finally, this study can be expected to obtain the intensity necessary for laser processing by controlling the intensity distribution of the laser diode array with Kinoform produced by error reduction algorithm.
