提出了一种利用共振三波相互作用在等离子体中操纵超强激光脉冲的有效方法。低质量的超强激光脉冲可以有效地转换成高质量的聚焦激光脉冲，而熵被共振等离子体波吸收。这可以在足够薄的等离子体层内实现，使得寄生散射和激光脉冲的不稳定性没有足够的时间发展。与等离子体中的激光脉冲压缩相结合，这一方案，例如使用为国家点火设施提供动力的激光器（例如，见国家点火设施项目网站：http：//www.llnl.gov/nif/project），有可能产生真空击穿强度。
An efficient way for manipulating ultraintense laser pulses in plasmas using resonant three-wave interactions is proposed. Poor quality ultraintense laser pulses can be efficiently transformed into high quality focused laser pulses, while the entropy is taken up by resonant plasma waves. This can be accomplished within plasma layers thin enough that parasitic scatterings and instabilities of laser pulses do not have enough time to develop. Combined with laser pulse compression in plasmas, this scheme, using, for example, the lasers that power the National Ignition Facility (see, for instance, the NIF project website: http://www.llnl.gov/nif/project), is potentially capable of producing vacuum breakdown intensities.
