Dynamically Stable Resonators

This book explores the concepts of dynamically stable resonators, systems in which there is a compromise between the stability range of the resonator and the size of the fundamental transverse mode, limited mainly by thermally induced birefringence, and their applications in linear and ring resonators of high-power Nd: YAG lasers. Theoretical foundations, birefringence compensation techniques and innovative solutions for different resonator configurations are presented. Experimental development includes systems pumped by commercial diode modules, capable of operating at a single frequency and with polarized output, reaching up to 55.6 W continuous. The work also adapts and expands classic formulas by Magni and Silvestri, allowing continuous and independent adjustments of the width and position of the stability interval. Combining solid theory and advanced experimentation, this book offers a comprehensive and applied view, making it a reference for researchers and professionals interested in high-power lasers and controlled stability.
