#### **Abstract**

considered femtosecond pulse energy scaling using dissipative soliton generation by two methods of solid-state and fiber mode-locked lasers. In Chapter 10, *Self-Focusing of High-Power Laser Beam through Plasma*, the authors study the beam laser characteristics during the interaction with generated plasma. They discuss the self-focusing and defocusing in laser

This book is a relevant reference source for researchers as well as engineers working with high-powered laser systems around the world. I would like to acknowledge my PhD advis‐ er Prof. Radovan Kovacevic who helped me with his great inputs, as well as my lovely wife

VIII Preface

Three high-power excimer laser systems with apertures of 25 and 40 cm of the output laser beam are described. The first and second laser systems consist of four and five excimer lasers, respectively. Third system consists of Ti:Sa front end and XeF(C-A) amplifier. The experimental results of the generation of the high-quality and high-power laser pulses are presented. Laser beams with pulse energy of up to 330 J (308 nm, 250 ns) and peak power 14 TW (450 nm, 50 fs) were obtained.
