High-energy, few-cycle THz pulse generation by high-intensity (∼1018 W/cm2) femtosecond laser with plasma mirrors have received significant attention in recent years [1-3]. This novel THz source has the potential of generating large bandwidth millijoule pulse energies, opening up applications in THz nonlinear optics, single-shot imaging and spectroscopy [4]. Solid density plasma shaping has already...
The Advanced Laser Light Source (ALLS) is a Canadian facility consisting of several high intensity laser systems based on Ti:Sapphire technology. These lasers deliver 25-35 fs laser pulse time duration, from 1 mJ up to 5 J energy per pulse, high repetition rate from 10 Hz to 5 kHz, and up to 200 TW of instantaneous power or 50 W of average power. The aim of this facility is, first to produce laser...
The Advanced Laser Light Source (ALLS) is a Canadian international research laboratory, aimed at exploring a new approach to the dynamic investigation of matter. We will review the ALLS capacities and its latest scientific results, with special emphasis on extreme plasma research.
We have demonstrated the generation of high harmonics (HHs) by using a laser-ablation plume. As a quite novel phenomenon, a single harmonic enhancement has obtained by using laser-ablation plumes with a strong oscillator strength transition material. We attribute the strong enhancement of single harmonic to multiphoton resonance with a strong radiative transition of the ion. For extending cut off...
