迄今为止，激光-等离子体相互作用的波长缩放实验仅限于相对适中的激光能量（EL≤ 200 J），短脉冲长度（τL≤ 2 nsec）和小焦斑直径（d λ，200 µm）。因此，等离子体的大小是相当适度的。在这些条件下，使用利弗莫尔的阿格斯激光器的波长缩放数据显示经典的吸收物理和不稳定性的证据很少，与简单的模型和计算机流体动力学计算吻合得很好。吸收和预热在短激光波长下表现得更有利。
Laboratory experiments on the wavelength scaling of laser-plasma interactions have thus far been restricted to relatively modest laser energies (EL≤ 200 J), short pulse lengths (τL≤ 2 nsec), and small focal spot diameters (d ≲, 200 µm). Thus the plasma sizes have been quite modest. Under these conditions, wavelength scaling data using Livermore’s Argus laser show classical absorption physics and little evidence of instabilities, in good agreement with simple models and with computer hydrodynamics calculations. Absorption and preheat behave much more favorably at short laser wavelengths.
