Abstract
In this paper we report a method for producing very small aperture lasers ( VSALs) from low-cost. commercial index guided edge emitting diode lasers. T he detailed fabrication procedure is provided and the VSALs are characteriz ed. Both high power and high aperture power to background noise power ratio are obtained even with a small aperture. This fabrication method can be ap plied to most commercial diode lasers without knowledge of the detailed geo metry and is highly reproducible.
