Experimental Analysis of Raman interactions underlying intracavity coupling of femtosecond soliton molecules — •Timo Wirth and Georg Herink — Experimental Physics VIII - Ultrafast Dynamics, University of Bayreuth, Germany

The phononic contribution of the nonlinear refractive index n2 governs bound states of femtosecond pulses or "soliton molecules" inside Ti:sapphire laser oscillators, as recently resolved via real-time spectroscopy [1]. In this contribution, we present an experimental analysis of the relative contribution of electronic and nuclear nonlinearities based on different extra-cavity detection schemes for time-resolved Raman spectroscopy. In particular, we compare results from impulsive stimulated Raman scattering (ISRS) obtained via optical Kerr effect (OKE), spectrally resolved two-beam coupling (SRTBC) and Kerr-lens spectroscopy. The latter detection scheme is closely related to intra-cavity soliton binding and yields quantitative insights into the fundamental soliton interaction.
