| 英文摘要 | In a heterostructure diode injection laser, the active layer has a region of relatively lesser thickness in registration with a stripe geometry contact. Increased gain within the region of lesser thickness relative to adjacent regions of greater thickness tends to effectively confine lasing operation to the thinner or constricted region. The dimensions of the constricted active region may be readily selected to discriminate against multifilament lasing modes in order to produce a single spot laser beam over a wide range of injection levels. |
