Abstract

In this paper, a subsystem of coupling semiconductor laser diode to the single-mode fiber and producing the diffraction-limited beam is described in detail, and beam wavefront is measured by a double shearing-interferometer experimentally. As a result, the divergence of the collimated beam is only 65.84μrad, which indicates that the transmitted beam achieves the diffraction-limited, and this optical subsystem is coincident very well with our design.
