Vertical External Cavity Surface Emitting Laser with Dielectric Film Integrated on Substrate
Vertical cavity surface emitting laser( VCSEL) with external cavity which is filled by dielectric materials or air can achieve good beam quality and high power. Aiming at the problem of complexExpand
Effect of Indium Tin Oxide as Transparent Conductive Layer on Shallow Surface Relief VCSEL
The mode stability of shallow surface relief vertical cavity surface emitting laser( VCSEL)is constrained by the nonuniform current density distribution in the active region. In order to solve thisExpand
An Optimized GAA Algorithm Used for Uniformity Improvement of Beam Shaping
An optimized generalized adaptive additive (GAA) method is proposed to improve the uniformity of output beam. Through analyzing different x factors in general GAA algorithm, which results in theExpand
Spatial Coherence of High Power VCSEL Triangular-array
The spatial coherence properties of high power vertical cavity surface emitting lasers( VCSELs) triangle-arrays were studied based on the theorem of Hermitian-Gaussian beams and spatial coherence.Expand
