Threshold solar power for dye laser pumping has been determined by measuring the gain of a rhodamine 6G dye laser amplifier at various solar-simulated irradiances on an amplifier cell. The measured threshold was 20 000 solar constants (2.7 kW/cm/sup 2/) for the dye volume of 2 x 5 x 40 mm/sup 3/ and the optimum dye concentration of 1 x 10/sup -3/ M. The threshold is about one-third of that achievable with a high-intensity solar concentrator.
