Paper Abstract

An essential component in laser diode array systems is the micro-optic system used for collimation and shaping of the output beams from indMdual elements of the laser array. Candidate micro-optic technologies include photolithic arrays, gradient-index optics, binary optics, and laser-assisted techniques. For the present work, a Mach Zender interferometer was constructed for evaluating wavefront quality. This instrument was used to select a lensiet array for an external cavity phase locking öxpement involving a 2 x 5 element monolithic surtace-emlthng laser diode array.
