| Popis: | Strained layer AlInGaAs-AlGaAs graded-index separate-confinement heterostructure single-quantum-well diode lasers with cavity width and length of 500 and 1000 mu m, respectively, have been operated continuous-wave (CW) at heatsink temperatures up to 125 degrees C, with output power up to 4.9 W per facet and power efficiency as high as 49% measured at 10 degrees C. Promising results have been obtained in initial reliability tests on uncoated devices at heatsink temperatures of 10 and 50 degrees C. > |
