Laser frequency upshift, self-defocusing, and ring formation in tunnel ionizing gases and plasmas

The combined effects of tunnel ionization of gases on laser frequency upshift, defocusing, and ring formation are considered self-consistently. A high-intensity short pulse laser causes rapid tunnel ionization of a gas. The increasing plasma density leads to a decreasing refractive index, modulating...
