Sunlight-Pumped Laser
Organic iodide gas is stimulated by portion of Sun's spectrum to emit laser light. Chopper forms pulses from beam of Xenon-Arc light. Chopper is only necessary to avoid buildup of laser-quenching species in sealed tube of present experiment. Perfluoropropyliodide lasing medium functions at temperatures of about 670 K, a fact that reduces cooling requirements in space.
