This book is designed to equip someone with minimal experience using lasers and optics with the knowledge and skills necessary to work effectively using an ultrafast laser system in their lab. This new edition features more information on different laser architectures, including explicit discussion of the differences between Ti:Sa and Yb:fibre lasers, and these are highlighted throughout where differences are relevant. Other sections have been expanded so that they now include better explanations and more context, content, and examples. ‘Ultrafast Lasers and Optics for Experimentalists (Second Edition)’ is intended for diverse audience: it codifies the basic principles of ultrafast laser operation and practical use, and explains key physical phenomena in an accessible and intuitive way, without recourse to dense mathematics.
