1. A diode laser package, comprising:
a plurality of flared laser oscillator waveguides arranged on a stepped surface to emit respective laser beams in one or more emission directions; a plurality of optical components situated to receive the laser beams from said plurality of flared laser oscillator waveguides and to provide the beams in a closely packed relationship; and an optical fiber optically coupled to the closely packed beams for coupling the laser beams out of the diode laser package; wherein said plurality of flared laser oscillator waveguides includes a first set of three or more of said flared laser oscillator waveguides arranged on a first stepped surface portion of said stepped surface at successive heights thereof such that a first set of beams is emitted parallel to each other and said first stepped surface portion in a first stepped configuration in a first emission direction; wherein said plurality of optical components includes a first set of optical components associated with said first set of three or more flared laser oscillator waveguides, said first set of optical components including fast-axis collimation optics and slow-axis collimation optics for collimating the respective fast and slow axes of the first set of beams and beam-turning optics coupled to each first set beam so as to provide each first set beam in a first set turn direction such that the first stepped configuration of beams becomes a first stacked configuration of beams; wherein said plurality of flared laser oscillator waveguides includes a second set of three or more of said flared laser oscillator waveguides arranged on a second stepped surface portion of said stepped surface at successive heights thereof such that a second set of beams is emitted parallel to each other and said second stepped surface portion in a second stepped configuration in a second emission direction opposite said first emission direction; wherein said plurality of optical components includes a second set of optical components associated with said second set of three or more flared laser oscillator waveguides, said second set of optical components including fast-axis collimation optics and slow-axis collimation optics for collimating the respective fast and slow axes of the second set of beams and beam-turning optics coupled to each second set beam so as to provide each second set beam in a second set turn direction parallel to said first set turn direction such that the second stepped configuration of beams becomes a second stacked configuration of beams.
