Coherently controlled generation of single-cycle terahertz pulses from thin layer of nonlinear medium with low-frequency resonances
R. M. Arkhipov, A. V. Pakhomov, M. V. Arkhipov +4
We propose a novel scheme to generate single-cycle terahertz (THz) pulses via reflection of an optical femtosecond pulse train from a thin layer of nonlinear resonant medium. Our m…
Self-induced transparency mode-locking in a Ti:sapphire laser with an intracavity rubidium cell
M. V Arkhipov, R. M. Arkhipov, A. A. Shimko +2
In a Ti:Sa laser with an absorbing with Rb vapor cell stable self-starting passive mode-locking is demonstrated. We show that the mode-locking appears due to self-induced transpare…
Passive and hybrid mode locking in multi-section terahertz quantum cascade lasers
P. Tzenov, I. Babushkin, R. Arkhipov +4
It is believed that passive mode locking is virtually impossible in quantum cascade lasers (QCLs) because of too fast carrier relaxation time. Here, we revisit this possibility and…
All-optical control of unipolar pulse generation in a resonant medium with nonlinear field coupling
A. V. Pakhomov, R. M. Arkhipov, I. V. Babushkin +3
We study optical response of a resonant medium possessing nonlinear coupling to external field driven by a few-cycle pump pulse sequence. We demonstrate the possibility to directly…
Few-cycle pulse-driven excitation response of resonant medium with nonlinear field coupling
A. V. Pakhomov, R. M. Arkhipov, I. V. Babushkin +1
We demonstrate that the resonant medium with essentially nonlinear field coupling can exhibit specific response when excited by the few-cycle optical pulse. We provide an effective…
Generation of unipolar pulses in a circular Raman-active medium excited by few-cycle optical pulses
R. M. Arkhipov, M. V. Arkhipov, I. Babushkin +3
We study theoretically a new possibility of unipolar pulses generation in Raman-active medium excited by a series of few-cycle optical pulses. We consider the case when the Raman-a…
Self-starting stable coherent mode-locking in a two-section laser
R. M. Arkhipov, M. V. Arkhipov, I. Babushkin
Coherent mode-locking (CML) uses self-induced transparency (SIT) soliton formation to achieve, in contrast to conventional schemes based on absorption saturation, the pulse duratio…
