Abstract

Summary form only given. Vertical cavity surface emitting laser diodes (VCSELs) are promising devices for optical pump sources due to their circularly symmetric beam profile. Their planar geometry also makes them uniquely suitable for ultra-compact, diode pumped lasers and laser arrays in which the pump source is directly bonded to the microchip. A further feature of the VCSELs is that their emitting aperture can be controlled to provide spatial variation of the pump power. We present, for the first time to our knowledge, a VCSEL pumped, plano-plano cavity, solid state laser and study the influence of the pump laser diameter on the operating characteristics.
