Potassium double tungstate waveguides with high ytterbium concentration for optical amplification

Abstract

Cover design: Three dimensional visualization of optical amplification in potassium double tungstate waveguide layer as a signal beam propagates from the top surface to the bottom surface. The model has a radius equivalent to about twenty times the optical beam's radius and only a quarter of the body is shown. The intensity of the signal beam is represented by the color spectrum (red being lowest and blue being highest). The wire frame is generated based on finite element mesh grids.
