Abstract
-
In this thesis, picosecond laser pulses are used to study the spectral and temporal properties of optical phonons in crystals using Raman Induced Phase-Conjugation Spectroscopy (RIPS). The concepts of RIPS are illustrated using a dynamical grating analysis. A theoretical description of the spectral properties of RIPS relying on the third order nonlinear susceptibility is worked out in detail for LiNbO{dollar}\sb3{dollar}. Optical phonon lifetimes are measured directly in real time using a new technique called STRIPS, which uses RIPS in conjunction with streak camera technology. This new technique is used to obtain information about the temperature dependence of phonon-phonon interactions of the 1086 cm{dollar}\sp{lcub}-1{rcub}{dollar} mode in calcite. Future directions for the use of RIPS in other areas of physics and photonics are suggested.
