复合型二元光学器件作为一种新型色散和相位补偿元件,由于其色散的特殊性,在超强超短脉冲激光的色散和波前补偿中具有特殊的意义。提出并研究了利用复合型二元光学器件同时补偿全钕玻璃啁啾脉冲放大(CPA)系统中的色散和相位畸变,并利用光线追迹的方法对二元光学器件模拟了设计和补偿效果。在实验中,利用二元光学器件将100 fs的光束补偿至30 fs左右。实验结果验证了此方法的可行性。

Composite binary optical elements are new dispersive and phasic compensation elements. For the unique dispersive characteristic , the elements have especial effect in dispersive and phasic compensation of ultrashort pulse. Using composite binary optical elements to compensate the dispersive and phasic error synchronously in the chirp pulse amplification (CPA) system is brought forword and studied. The design of binary optical elements, simulation and experiments of dispersive compensation are performed in ray tracing method. 100 fs pulse is compressed to about 30 fs by using the binary optical elements. The experiment results prove the way feasible.
