Green Laser Beam on Optical Table at Night

A sharp green laser beam stretches horizontally across a darkened optical table, its path defined by the neon-reflected light of the laboratory. The setting rests inside a bright room in Santiago de Cuba, where early summer conditions are managed by the indoor environment. Muted reflections of the equipment stretch along the polished concrete floor, creating depth beneath the machinery. Metal components of the optical table gleam under the artificial light, standing against the deep shadows of the darkened corners. The beam remains steady and straight, a line of pure energy against the complex array of lenses and mounts. At the edge of the frame, a small dust mote catches the light near the beam's endpoint, marking the precision of the experiment in this quiet, nocturnal setting.
