全息图通过在记录介质中压印场和参考光束之间的干涉来完全编码三维光场。在这里，我们表明，两个共线泵浦激光器与不同的焦点重叠在一个气体射流产生的全息等离子体透镜能够聚焦或准直探测激光的强度几个数量级高于非电离光学的限制。我们概述了这些衍射等离子体透镜的理论，并提出了两个等离子体机制，使他们的建设模拟：空间变化的电离和ponderomottively驱动的离子密度波动。抗损伤的等离子体光学器件是操纵高强度光所必需的，而由全息等离子体透镜提供的高强度脉冲的发散控制将是高功率等离子体激光器的关键组成部分。
A hologram fully encodes a three-dimensional light field by imprinting the interference between the field and a reference beam in a recording medium. Here we show that two collinear pump lasers with different foci overlapped in a gas jet produce a holographic plasma lens capable of focusing or collimating a probe laser at intensities several orders-of-magnitude higher than the limits of a nonionized optic. We outline the theory of these diffractive plasma lenses and present simulations for two plasma mechanisms that allow their construction: spatially varying ionization and ponderomotively driven ion-density fluctuations. Damage-resistant plasma optics are necessary for manipulating high-intensity light, and divergence control of high-intensity pulses-provided by holographic plasma lenses-will be a critical component of high power plasma-based lasers.
