Compression of multi-mJ, 35-fs to the few-cycle regime — •Yinyu Zhang1, Philipp Wustelt1,2, Max Moeller1,2, Max Sayler1, and Gerhard Paulus1,2 — 1Institute for Optics and Quantum Electronics, Jena, Germany — 2Helmholtz Institut Jena, Jena, Germany
Laser pulses of few optical cycles duration and high pulse energy have become fundamental tools for many ultra-intense and ultrafast nonlinear science experiments, such as high-harmonic generation (HHG) and attosecond physics. Here we present a study of few-cycle pulses with multi-mJ pulse energy from a Ti: Sapphire laser system with 35-fs pulse duration. The pulse compression by a hollow core fiber (HCF) filled with gradient pressure of noble gases and filamentation were studied. The experimental parameters and the compression results from two compression mechanisms were compared.
In addition, the efficiency of coherent pulses combination of delayed pulses were tested for compression through a HCF and filamentation. The birefringent crystals, quartz and calcite with different thickness were used for temporal pulse division and coherent combination. Pulses with 10-fs pulse duration and multi-mJ energy were generated with different compression techniques
