点火实验的辐射流体动力学模拟表明，交叉激光束之间的能量传递可以调节内爆对称。建立了一种新的全尺寸三维交叉光束能量传递定量模型，可以计算多个激光束及其相关等离子体波在点火腔中的传播和耦合。该模型已在辐射流体力学代码中实现，演示了通过激光束锥之间的波长分离来控制内爆对称性。
Radiative hydrodynamics simulations of ignition experiments show that energy transfer between crossing laser beams allows tuning of the implosion symmetry. A new full-scale, three-dimensional quantitative model has been developed for crossed-beam energy transfer, allowing calculations of the propagation and coupling of multiple laser beams and their associated plasma waves in ignition hohlraums. This model has been implemented in a radiative-hydrodynamics code, demonstrating control of the implosion symmetry by a wavelength separation between cones of laser beams.
