摘要:
Detailed calculations have been performed to show the importance of refractive effects on laser‐induced breakdown in gases. The refraction, which results from gradients in the density of plasma electrons, can cause a loss of energy from the beam and an apparent dependence of breakdown threshold on beam or focal spot size.
