摘要

在飞秒全息激光加工中，精确控制由计算机生成的全息图(CGH)重建的衍射图样是非常重要的。由于飞秒激光脉冲引起的现象是基于非线性光学效应的，为了获得理想的衍射图，在光学装置中对衍射图产生的二次谐波进行了估计，并进行了优化。实验验证了所提出的二次谐波优化算法的有效性。

Optimization of computer-generated hologram using second harmonic generation

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.
