Atomic Oxygen Generation by Laser Plasma as a LEO Environmental Simulator
説明
High speed atomic oxygen flows were generated by a laser driven plasma wind tunnel to simulate low earth orbit environment. The flow velocity was measured by laser absorption spectroscopy using OI 777.19 nm line. Using pure oxygen as a working gas, the flow velocity was 5.4 km/s. To enhance the velocity, average molecular weight was reduced by mixing helium. As a result, the velocity increased to 6.2 km/s for the laser power of 1300 W, oxygen flow rate of 1.2 slm and helium flow rate of 0.3 slm.
