Combined dc electric-ultraviolet to near infrared optical breakdown of Ar in a wide range of impact parameters

A combined dc electric-optical breakdown (λ = 213, 266, 355, 532 and 1064 nm; τFMWH = 68 ps, 18 ns; I0 = 109-1013 W cm2; Edc = 0-13.2 kV cm) and discharge dynamics in argon has been experimentally investigated at pressures (p = 1.0 × 101-5.57 × 105 Pa). Breakdown thresholds were evaluated at differe...

Summary:A combined dc electric-optical breakdown (λ = 213, 266, 355, 532 and 1064 nm; τFMWH = 68 ps, 18 ns; I0 = 109-1013 W cm2; Edc = 0-13.2 kV cm) and discharge dynamics in argon has been experimentally investigated at pressures (p = 1.0 × 101-5.57 × 105 Pa). Breakdown thresholds were evaluated at different gas pressures and irradiation wavelengths for 0.5 breakdown probability in terms of laser and electric components. It has been discovered that such a combined breakdown could take place at laser and electric components values significantly less than those for "pure" optical or electric impact.
