Precision-aligned co-collimated infrared (IR) and visible light beams were efficiently generated and simultaneously delivered via a transmitter, which was constructed by exploiting an integrated optic beam aligner in conjunction with a collimating lens. The beam aligner comprises two optimally separated silica waveguides preventing mode coupling, and delivers parallel beams at \lambda=905 and 650 nm. The aligner was fiber-pigtailed to the corresponding laser diodes and combined with an aspheric lens to construct a miniature dual-laser transmitter. Gaussian-like IR and visible beams, with divergence angles of 0.085 and 0.09°, respectively, were highly aligned with an angle of 0.075°.
