Abstract

Two-mirror beam shaping of a 94% fill-factor laser diode bar was investigated. We show that optimal output for the purposes of end pumping was achieved by configuring the beam shaper to reformat the single row of 60 emitters into an array containing several emitters in each row. A 15×4 output configuration was used to end pump a Yb:S-FAP laser. A nearly on-axis multipass pumping system was developed to demonstrate how the asymmetry of the beam-shaped pump source can be exploited.

Plan view of diode-bar beam-shaping setup. The diode output is imaged at the beam shaper BS in the x z plane with cylindrical lenses CL1 ( f = 100 mm ) and CL3 ( f = 200 mm ) , and collimated in the y z plane by the microlens ML and CL2 ( f = 76.5 mm ) . The shaped output is brought to a spot by spherical achromat SA1 ( f = 200 mm ) and CL4 ( f = 50 mm ) . Wave plates WP1 and WP2 were added to preserve polarization through the shaper.
