The lunar Orbiter laser Altimeter (LOLA) works by sending a laser pulse through an optical lense that splits it into five beams that are each scattered back after they strike the lunar surface.
For the impulse, the two-photon reactions were dominated by the initial primary (unscattered and unabsorbed) pulse and the single—photon reactions were dominated by the scattered diffuse light.
