Ti:sapphire Laser Oscillators
The development, characterization and application of Ti:sapphire lasers has been a mainstay of our group for years. Currently Ti:sapphire lasers developed by our group hold the distinction of generating the shortest as well as the most energetic laser pulses ever achieved from Ti:sapphire oscillators. Using these unique laser systems allows us to investigate numerous areas in fundamental physics with exceptional precision.
- Oscillator Pulse Train with Constand Carrier-Envelope-Offset Phase
- Microjoule Pulse Energies From a Ti:Sapphire Oscillator
- 4 fs Ti:sapphire oscillator with octave-spanning spectrum
Applications:
Few-Cycle Oscillator Pulse Train with Constant Carrier-Envelope-Phase
In this project an octave-spanning Ti:sapphire laser oscillator stabilized to carrier-envelope-offset frequency zero is developed, generating a pulse train with constant field profile for every pulse. Stabilization is realized using an extended self-referenced locking scheme enabling
to lock the carrier-envelope-offset phase with less than 65 attosecond rms timing jitter. [more...]
Microjoule Pulse Energies from a Ti-Sapphire Oscillator
Currently applications which require fs - pulse durations and pulse energies in the µJ regime rely solely on Ti-Sapphire amplifier systems. Those systems are commercially available and can readily supply pulse energies up to several mJ. However the drawback of these systems is that they are somewhat complex, expensive and that their repetition rate (frep) is limited to the kHz regime. [more...]
4 fs Ti:sa oscillator with over octave-spanning spectrum
The aim to generate laser pulses in the sub-5 fs domain towards the single-cycle limit (for Titanium:sapphire 2.7fs @ 800nm) is still one hot topic in nowadays laser science.
Those laser systems with octave-spanning sprectra are on the one hand interesting for high resolution optical coherence tomography (OCT), and in combination with a pulse shaper they build a powerful light source for spectroscopic experiments. [more...]
