On the basis of real-time {\it ab initio} calculations, we study the non-perturbative interaction of two-color laser pulses with MgO crystal in the strong-field regime to generate isolated attosecond pulse (IAP) from high-harmonic emissions from MgO crystal.
In this regard, we examine the impact of incident pulse characteristics such as its shape, intensity, and ellipticity as well as the...
Atoms and molecules in electronically excited states are referred to as metastable, if their decay to lower-lying states is forbidden by electric-dipole selection rules. Owing to their high electronic energy, metastable species can induce the ionization of other atoms or molecules upon collision, a process often referred to as autoionization. Autoionization processes are of great importance in...
Superconducting radio frequency (SRF) niobium cavities are the basic building blocks of linear accelerators present in modern x-ray free electron lasers, such as the European X-Ray Free-Electron Laser. The final surface treatment steps of Nb cavities impose a subtle change in their performance to obtain high quality factors at high accelerating field gradients; however, the underlying physical...
Photo Injector Test facility at DESY in Zeuthen (PITZ) utilizes slit scan technique as a standard tool for reconstruction of horizontal and vertical phase spaces because of its space charge dominated electron beams. A novel method for 4-dimensional transverse beam phase space measurement is proposed at PITZ known as Virtual Pepper Pot that can give insight to transverse beam phase space...
