FIGURE 1. Transforming bacteria into solar-powered lasers: we extract light-harvesting structures from bacteria (left), enhance them with proprietary specially engineered lasing units (middle), and place them into a lasing cavity (right) to create a new type of laser that runs directly on sunlight. The natural light-gathering rings (green/purple) of purple bacteria measure 60-nm across and achieve near-perfect efficiency in energy transfer of captured photons.
