Abstract

Ultrashort pulse lasers have become a comprehensive tool for various applications, such as ultrafast spectroscopy, imaging, and material processing, owing to their broad spectrum, short time resolution, and high peak power. A Ti:sapphire is known as one of the most promising gain materials for ultrashort pulse lasers, and modelocking (ML) techniques of Ti:sapphire lasers have been developed for several decades.
