Compact Sub-50 fs Lasers for Time-Domain Kerr-Effect Spectroscopy

Time-domain spectroscopies based on the optical Kerr effect (OKE) can provide a glimpse into the ultrafast processes that dictate fundamental properties of material and biological samples. Such experiments can provide insights into molecular interactions and energy transfer processes that could facilitate improved solar cell efficiencies, better pharmaceuticals, and new photonics devices.

Until recently, OKE has been confined to academic research labs due to the limited availability of laser sources with sub-50 fs pulse durations. In this white paper, a compact, commercially available fiber-based fs laser was used to verify the capability of such laser sources for OKE and Raman-induced Kerr effect spectroscopy (RIKES).
