Nichtlineare optische Spektroskopie an Grenzflaechen

Nonlinear optical spectroscopies using second-harmonic and sum-frequency generation are powerful techniques to examine properties of surfaces and interfaces. However, they have been applied only rarely so far, mainly because appropriate high-power laser systems with large and easy tunability are not commonly available. This work discusses the development of such a tunable laser source as well as the experimental setup for nonlinear-optical spectroscopy of surfaces and interfaces which is applied to the investigation of electronic and vibrational properties of silicon surfaces and interfaces.
