Abstract :
Room-temperature laser oscillation at 469 nm observed in photopumped bulk ZnSe is discussed. The result was obtained by using a pump photon energy very close to the bandgap energy and by enhancing the resonator Q with high-reflectivity coatings. Threshold pump power densities as low as 370 kW/cm/sup 2/ were measured.<>
