Experiment and Theory: (Left) Ti:S femtosecond oscillator in action.  Our Coherent Mira is pumped with 10 W of 532 nm light.  (Right) Time dependence of the electric field of an ultrafast pulse (http://web.iitd.ac.in/~kumarsunil/research.html).

PHYS 5130: Ultrafast Spectroscopy 


Ultrafast phenomena (processes, pulses, fluctuations, etc.) occur on the 1 to 1000 fs time scales.  Although recent advances with high harmonic generation have created pulses faster than this, the ultrafast regime continues to be a central focus in physics, chemistry, electrical engineering, and bio-medical engineering.  Beyond scientific advances, the advent of lasers with higher powers, increased stability, and greater spectral ranges makes ultrafast technology an increasingly more important tool for applications.  In this course, we will study population inversion, lasing, mode-locking, mathematical descriptions of pulses, measuring ultrafast pulses, harmonic and difference-frequency generation, and terahertz time-domain spectroscopy.
