摘    要:为了研究飞秒激光时空变换整形技术,采用理论分析与计算机模拟结合讨论的方法,分析了以达曼类滤波器为模板的4f 系统的飞秒脉冲整形技术。以梯度算法优化设计出达曼类滤波器,包括等间距、等强度和不等间距、不等强度达曼光栅,并模拟讨论了产生的超快时域多脉冲与光谱平面上调制周期的重复数、元件间距不等效应和波长效应的影响。结果表明,以达曼类滤波器为模板的飞秒脉冲整形中,模板周期重复数越多,输出脉冲的质量越高;元件间距不等和波长效应使输出脉冲的平均度和衍射效率都有所降低。

关 键 词:光学器件    超快光学    飞秒整形    时空变换    达曼类滤波器

Abstract:Progress on femtosecond pulse shaping with space-time conversion technique and recognition for Dammann-type filters is analyzed in this paper. We designed the multiple pulses Dammann-type filter. With the simulation of a Gaussian spectral distribution, we realize that the perfect uniformity of the generated multiple ultrafast temporal pulses is relevant to he periodic repetition number, the spacing between the components and the modulated phase plate with the wavelength in the mask in the spectral plane. Moreover, experiment characterization of pulses two femtosecond pulses by the frequency-resolved optical gating (FROG) characterization technique is also given.
Keywords:optical device  ultrafast optics  femtosecond pulse shaping  space-time conversion  Dammann-type filter
