Q switching by self-focusing [PDF]
Optics Letters, 1985 A novel passive technique for obtaining short-laser-pulse emission is presented. A cell with a high-second-order refractive-index liquid is included in an unstable laser cavity. The external self-focusing introduced by the cell at higher optical intensities reduces the diffraction losses, producing modulation of the gain and Q switching of the cavity ...

Graphene Q-Switched Mode-Locked and Q-Switched Ion-Exchanged Waveguide Lasers [PDF]
IEEE Photonics Technology Letters, 2015 In this letter, we present the use of monolayer graphene saturable absorbers to produce Q-switched and Q-switched mode-locked operation of Yb and Yb:Er-doped phosphate glass waveguide lasers, respectively. For the 1535-nm-wavelength Yb:Er laser, the Q-switched pulses have repetition rates up to 526 kHz and contain mode-locked pulses at a repetition ...

Multi-Agent Dynamic Resource Allocation in 6G in-X Subnetworks with Limited Sensing Information
Sensors, 2022 In this paper, we investigate dynamic resource selection in dense deployments of the recent 6G mobile in-X subnetworks (inXSs). We cast resource selection in inXSs as a multi-objective optimization problem involving maximization of the minimum capacity ...

High speed quantum gates with cavity quantum electrodynamics [PDF]
, 2008 Cavity quantum electrodynamic schemes for quantum gates are amongst the earliest quantum computing proposals. Despite continued progress, and the dramatic recent demonstration of photon blockade, there are still issues with optimal coupling and gate ...
