Abstract

We describe for the first time to our knowledge the performance for a linear array of tapered laser diodes with both fast- and slow-axis collimation using a microlens for fast-axis collimation and a laser-written phase plate for slow-axis collimation and correction of the residual fast-axis errors from lens aberrations, thermal lensing, astigmatism, pointing errors, and other wavefront distortions. The phase plate leads to M2 factor reductions of 1.5 for the lensed array following the fast axis and 2.6 for the whole bar following the slow axis. © 2007 Optical Society of America.
