摘要: Laser‐induced breakdown in very clean air at 10.6 μm is shown to have a threshold of 3 × 109 W/cm2 for large beams and described well by microwave theory. Dust particles are lower the an amount which greater larger higher vapor temperatures. There minimum particles, 200‐nsec pulse length ≤ 108 W/cm2, corresponding energy fluence 10–20 J/cm2. These results explained qualitatively increase inverse bremsstrahlung rate caused exploding particles.
