Sequential power transfer between stripes of a diode laser array via photorefractive two-wave mixing in BaTiO3

Sequential power transfer between stripes of a diode laser array via photorefractive two-wave mixing in BaTiO3
Sequential power transfer between stripes of a diode laser array via photorefractive two-wave mixing in BaTiO3
We report the transfer of 48% of the incident power from a semiconductor laser array into a diffraction-limited beam by means of photorefractive coherent beam combination in BaTiO3, using a progressive two-wave mixing geometry. A single-element, photorefractive beam combiner is described which should allow the transfer of 88% of the power of a suitable array into a single diffraction-limited beam.

Abstract

We report the transfer of 48% of the incident power from a semiconductor laser array into a diffraction-limited beam by means of photorefractive coherent beam combination in BaTiO3, using a progressive two-wave mixing geometry. A single-element, photorefractive beam combiner is described which should allow the transfer of 88% of the power of a suitable array into a single diffraction-limited beam.
