| 英文摘要 | A diode laser of the type having an array of laser emitters in a Talbot cavity in which edge reflectors are added to enhance feedback to edgemost emitters. In one embodiment, a transparent slab with reflectively coated sides is present between the phase plane of the emitted light and the Talbot cavity reflector. The phase plne is defined by a lenticular array placed a focal length in front of the laser emitters. In another embodiment, the Talbot cavity reflector has an increased reflectivity toward its edges. In all embodiments the Talbot cavity reflector is preferably spaced a distance na2/ lambda from the phase plane, where n is a positive integer, a is separation between adjacent emitters and lambda is the wavelength of emitted light. An integrated embodiment has the array and cavity reflectors defined ina single semiconductor body divided into active and ransparent region. Side mirrors are etched into the semiconductor body. The laser array may also be extended to two dimensions with individual lasers or laser bars fiber coupled to a lens surface, with an edge reflector and Talbot cavity reflector coated on an otherwise transparent slab. |
