Abstract

The thesis deals with a novel type of solid-state lighting – laser diode lighting. Laser diode lighting is based on the use of a blue laser diode to excite a phosphor material that will generate white light. Laser diode lighting possesses unique characteristics of the generated light, enabling delivery of a high luminance output from small emitting areas. In the thesis, a novel laser based light source was demonstrated and investigated. Initially, saturation effects in ceramic phosphors are described. Saturation is among the key factors limiting performance of high power laser diode lighting systems. Subsequently, a propagation of laser light in a phosphor medium is studied. An experimental and a numerical investifation is presented. And lastly, an endoscopic light source based on a phosphor converted laser diode is designed and characterized.
