Portable Diode Pumped Femtosecond Lasers

Mehr zum Buch

Focusing on advancements in ultrashort pulse laser technology, this thesis explores efforts to miniaturize and reduce costs while enhancing applications such as terahertz radiation and ultrastable atomic clocks. Key concepts include mode locking and intracavity group velocity dispersion, with an emphasis on cavity design and crystal selection for solid state lasers. The research compares small cavity systems to commercial titanium-sapphire lasers, highlighting the influence of equipment and materials on pulse generation. Despite challenges, it sets the stage for future developments in portable femtosecond lasers.
