Annotation -
Ultrashort laser pulses have applications in many fields of physics or chemistry for measurement of ultrafast phenomena occurring on short timescales (typically ps-ns). This lecture is focused on the introduction to the physics of ultrashort laser pulses with time durations in the femtosecond domain. We will discuss practical and theoretical concepts related to linear and nonlinear optical phenomena related to ultrashort pulse propagation in matter, their generation, practical applications and characterization of their properties.
