One new method is proposed to synthesize a laser field via the superposition of single-color and hyper-Gaussian pulses. The numerical analysis confirms that our scheme is efficient for the production of an isolated super-bright attosecond pulse of a sub-atomic unit by controlling the hyper-Gaussian parameter, which could provide one way for the final realization of an attosecond pump and attosecond probe technique. Finally, we further demonstrated the experimental feasibility of this method by examining the dependence of the higher-order generation spectra on the laser wavelength and intensity.

通过双色高斯脉冲生成亚原子单位阿秒脉冲

提出了一种通过单色和高斯脉冲的叠加来合成激光场的新方法。数值分析证实，通过控制超高斯参数，我们的方案对于产生亚原子单元的孤立超亮阿秒脉冲是有效的，这可以为最终实现阿秒泵和阿秒探针提供一种方法技术。最后，我们通过检查高阶谱对激光波长和强度的依赖性进一步证明了该方法的实验可行性。
