Lecture

Laser Amplification: Stimulated Emission and Mode-Locking

Description

This lecture covers the principles of laser amplification through stimulated emission, including axial modes, resonant frequencies, and population inversion. It also delves into the generation of short pulses using mode-locking techniques, such as acousto-optic modulators and frequency modulation. The instructor discusses the importance of phase relations between modes for achieving short pulse durations and high intensities, as well as the influence of cavity modes on pulse generation. Various references on laser physics and pulse generation are provided for further reading.
