Enhancing Quantum Control by Improving Shaped-Pulse Generation

Quasi-half-cycle terahertz pulse generation via optical rectification in quantum wells using shaped optical pulses.

It is shown that optical rectification in biased quantum wells using specially shaped optical pulses can be used to generate quasi-half-cycle THz electromagnetic pulses. Namely, we investigate THz generation by pulses incorporating a rapid pi phase shift. We further explore the potential of this scheme for high-repetition-rate quasi-half-cycle THz pulse generation.

Coherent control of terahertz harmonic generation by a chirped few-cycle pulse in a quantum well

We present results on the occurrence of ultrashort terahertz harmonic generation (THG) driven by a millimeter nonlinear chirped few-cycle laser pulse in a symmetric double quantum well. By solving the effective nonlinear Bloch equations, THG with a generic plateau and cutoff can be produced. The time–frequency characteristic of the ultrashort terahertz harmonic spectrum is analyzed in detail by...

Improving continuing medical education by enhancing interactivity: lessons from Iran

Introduction: Continuing Medical Education (CME) has beenconsidered as a lifelong commitment for doctors to provide theoptimal care for patients. Despite a long history of creating CMEprograms, outcomes are far from ideal. The present qualitativestudy aims to clarify the barriers affecting effectiveness of the CMEprograms in Iran based on the experiences of general practitioners.Methods: Sixtee...
