| 中文摘要 | high-power operation of uncoated 22-mu m-wide quantum cascade lasers (qcls) emitting at lambda approximate to 4.8 mu m is reported. the emitting region of the qcl structure consists of a 30-period strain-compensated in0.68ga0.32as/in0.37al0.63as superlattice. for a 4-mm-long laser in pulsed mode, a peak output power is achieved in excess of 2240mw per facet at 81k with a threshold current density of 0.64ka/cm(2). the effects of varying the cavity lengths from 1 to 4mm on the performances of the qcls are analysed in detail and the low waveguide loss of only about 1.4 cm(-1) is extracted. |
