Seminario: Ultrafast optics con Ursula Keller

Prof. Ursula Keller

Lunes 10 de marzo, 10 a 13 h. Aula 1401, Edificio Cero + Infinito.

Introduction to Mode Locking and Frequency Combs 
These lectures will provide foundational knowledge based on Keller's textbook, *Ultrafast Lasers* (Springer Verlag)

• Basic principles and motivation: Modelocked lasers and their impact for many new discoveries
• Linear pulse propagation in time and frequency domain
• Active modelocking: Siegman-Haus theory
• Passive modelocking with and without dynamic gain saturation
• Passive modelocking: Fast saturable absorber
• Problems with self-starting, Q-switching, long open net-gain window, too much SPM
• Passive modelocking: Soliton modelocking
• Frequency comb and CEO phase stabilization CEO: carrier envelope offset phase
• New concepts: Dual-comb modelocking

Miércoles 12 de marzo, 10 a 13 h. Aula 1401, Edificio Cero + Infinito.

Attosecond Measurements and the Unresolved Question of Tunneling Time 
A graduate-level introduction to ultrafast measurement techniques (e.g., pump-probe, streaking, etc.) followed by a detailed discussion on tunneling time measurements and their unresolved aspects.

• Time in Quantum Mechanics is challenging (more later with tunneling time)

• Motivation for THz to PHz Spectroscopy

• High Harmonic Generation (HHG) and attosecond pulses

• Attosecond Streak Camera

• RABBITT

• Conclusion and Outlook
