Laser startup optics for Baseball II and future mirror machines

PDF Version Also Available for Download.

Description

The laser startup system for Baseball II-T uses a 300-J CO$sub 2$ laser to hit a 100-$mu$ diameter pellet with a laser power density on the order of 10$sup 13$ W/cm$sup 2$. The laser is a 20-cm diameter unstable resonator transversely excited (TEA) oscillator. The beam is split and then focused using off-axis parabolas. The symmetric configuration and central obscuration of the CO$sub 2$ beam allow coaxial alignment and pellet detection optics. This experiment primarily uses commercially available systems and components. Optical elements were fabricated both by direct machining and standard polishing techniques. The laser and optical systems are directly ... continued below
