1. A method for efficient collimation of an aligned multiple beam output coupled from a diode laser bar to a lens system to conserve source brightness and output uniformity, comprising the steps of:

  • orienting the laser diode bar having multiple beam outputs substantially in straight-line alignment in a manner that its longitudinal length is aligned along a direction substantially parallel to a gravity vector; and

    orienting the lens system in a manner that its longitudinal axis is aligned along a direction substantially parallel to the gravity vector so that both the laser diode bar and the lens system are prevented from sagging as in the case where its longitudinal axis is aligned along a direction substantially perpendicular to the gravity vector so that substantially straight-line alignment of the lens system is maintained with the straight-line alignment of the multiple beam outputs.
