| 英文摘要 | The development of quantum cascade laser at 2.94 thz is reported. the laser structure is based on a bound-to-continuum active region and a semi-insulating surface-plasmon waveguide. lasing is observed up to a heat-sink temperature of 70 k in pulsed mode with light power of 4.75 mw at 10 k and 1 mw at 70 k. a threshold current density of 296.5 a/cm(2) and an internal quantum efficiency of 1.57 x 10(-2) per cascade period are also observed at 10 k. the characteristic temperature of this laser is extracted to be t(0) = 57.5 k. |
