A laser synthesis scheme via the superposition of single-color and hyper-Gaussian pulses is proposed, and the synthesized laser pulse is adopted to interact with pre-aligned molecules for the production of an isolated attosecond pulse (IAP). The numerical results based on strong-field approximation disclose that the proposed scheme is efficient for the generation of an IAP under suitable hyper-Gaussian parameters, and the intensity of an IAP is sensitive to molecular pre-alignment angles, and thus an optimal set of hyper-Gaussian parameters and pre-alignment angles can support the strongest IAP.

通过激光合成从排列的分子中产生孤立的阿秒脉冲

提出了一种单色和超高斯脉冲叠加的激光合成方案，采用合成的激光脉冲与预先排列好的分子相互作用，产生孤立的阿秒脉冲（IAP）。基于强场近似的数值结果表明，在合适的超高斯参数下，该方案对于生成 IAP 是有效的，并且 IAP 的强度对分子预对准角敏感，因此是一组最优的超高斯参数和预对准角度可以支持最强的 IAP。
