提出了用于飞秒激光脉冲优化整形的声光可编程色散滤波器的一阶操作理论。讨论了滤波器的光谱分辨率、角孔径、编程点数、衍射效率与声功率的关系。该理论考虑了二氧化碲晶体引起的色散效应。滤波器的宽带或高分辨率操作导致两种不同的晶体切割优化。该滤波器的应用涉及：1)激光链中高阶相位畸变和增益变窄的同步补偿；2)原子、分子和凝聚态物理中电子或振动跃迁的相干控制。
A first order theory of operation of the acousto-optic programmable dispersive filter used for femtosecond laser pulse optimization and shaping is presented. The filter spectral resolution, angular aperture, number of programming points, diffraction efficiency as a function of acoustic power are addressed. The theory takes into account the dispersion effects induced by the Tellurium dioxyde crystal. Wideband or high resolution operations of the filter lead to two different crystal cut optimizations.The applications of the filter concern: i) the simultaneous compensations of high orders phase distorsions and of gain narrowing in laser chains, ii) the coherent control of electronic or vibrationnal transitions in atomic, molecular and condensed matter physics.
