... The OH radicals are detected via laser-induced fluorescence with a continuous wave ring dye laser system (Coherent 899-21) that is actively stabilized. The dye-laser radiation is frequency doubled in an external cavity, where typically a power of 4 mW is obtained with a bandwidth of 2 MHz. The lase ...

Quantum vacuum thruster
A quantum vacuum plasma thruster (or Q-thruster) is a proposed type of spacecraft thruster that would work in part by acting on the virtual particles produced by quantum vacuum fluctuations. This was proposed as a possible model for an engine that could produce thrust without carrying its own propellant. Some physicists working with microwave resonant cavity thrusters think that they might be the first examples of such an engine.
