Leerdoelen  At the end of the course, the student is able to: 1. identify 1) common ultrashort laser systems and their spectral regimes 2) several pumpprobe techniques 3) conditions under which spectral dispersion affects the pulse length 4) The various temporal regimes over which specific interactions take place (electronelectron scattering, electronphonon scattering, exciton formation) 2. Through 2 tutorials, students are able to calculate 1) Dispersion of material 2) Estimation of time constants 3) Fitting of time resolved data to a model for pumpprobe 3. complete a practicum demonstrating 1 of 2 competencies: 1) Spectrally resolved autocorrelation. Students will construct an instrument for autocorrelation and measure the spectral dispersion of several of several dielectric materials.2) Pumpprobe spectroscopy of a model system. 4. analyse their practicum results to: 1) For practicum #1: The extracted wavelength dependent dielectric constant will be compared to known values from literature. 2) For practicum #2: students will fit the results and interpret the measured time constants within the framework of a known model 

Omschrijving  Ultrafast dynamics in materials play a fundamental role across a wide spectrum of physics, biology, and chemistry. The thermalization of heat in micro and nano electronics, the initial steps in vision, and the generation of electricity from solar radiation all rely on processes that are measured in femtoseconds to picosecond and nanoseconds. The course aims to understand such processes by studying material systems ‘in real time’, providing direct visualization of these processes at extreme timescales, and covers the following topics: 1. General concepts and principles 2. Ultrashort pulses: generation and characterization 3. Ultrafast spectroscopist’s toolkit 4. Dynamics in small molecules 5. Dynamics in Macromolecular systems 6. Dynamics in extended systems

Entreevoorwaarden  The course unit assumes prior knowledge acquired from compulsory courses taught at the degree programmes MSc Physics: Advanced Materials, MSc Applied Physics, MSc Chemistry: Advanced Materials, TopMaster in Nanoscience. The following preceding courses are considered advantageous: Characterisation on Materials, Laser Physics, Nonlinear Optics.  
Opmerkingen  The exam mark scales linearly with the number of pointes obtained by the student, with an offset. The following equation is used: Exam_Mark = (Points scored)/(Maximal number of points that can be scored)*9+1. Therefore, if 75% of scored points result in the mark of 7.75; 100% is translated to the mark of 10. The final mark is a weighted average of the marks for the practicum and exam: Mark = 0.3*Pra This course was registered last year with course code WMPH13007
