This research uses a two-color pulse system and polarization gating technique to generate single attosecond pulses from femtosecond laser interaction with cadmium sulfide semiconductor. The rotating elliptical polarization two-color pulse system is designed to produce attosecond pulses up to 420 as. Also, the intensity of the single attosecond pulse can be improved by using a two-color-polarizing gate technique. In this presented modifications, the isolated attosecond pulse with greater intensity and a shorter time width of about 400 as is generated. Generation of such an intense isolated attosecond pulse is a great achievement that helps for measuring the ultrafast phenomena.
本研究采用双色脉冲系统和偏振选通技术,通过飞秒激光与硫化镉半导体相互作用产生单个阿秒脉冲。旋转椭圆偏振双色脉冲系统旨在产生高达420阿秒的阿秒脉冲。此外,使用双色偏振选通技术可以提高单个阿秒脉冲的强度。在本研究提出的改进中,产生了强度更高、时间宽度约为400阿秒的孤立阿秒脉冲。产生如此强烈的孤立阿秒脉冲是一项重大成就,有助于测量超快现象。
