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。
As a new type of dispersion and phase compensation element, compound binary optical device has special significance in the dispersion and wavefront compensation of super-short pulse laser due to the particularity of its dispersion. Proposed and studied the use of composite binary optics to simultaneously compensate for chromatic dispersion and phase distortion in a full neodymium glass chirped pulse amplification (CPA) system, and the design and compensation effects of the binary optics were simulated using ray tracing. In experiments, a binary optical device was used to compensate a beam of 100 fs to about 30 fs. The experimental results verify the feasibility of this method.
