Precise control of a diffraction pattern reconstructed from a computer-generated hologram (CGH) is very important in holographic femtosecond laser processing. To obtain a desired diffraction pattern, an optimization based on an estimation of the second harmonic wave generated by the diffraction pattern in the optical setup is performed, because the phenomena induced by a femtosecond laser pulse is based on nonlinear optical effects. The second harmonic optimization we named is performed experimentally and the effective performance is demonstrated.
