Competition and bistability of longitudinal modes in a Raman laser [PDF]
A model for Raman lasers including several longitudinal modes is analyzed. Depending on the choice of the parameters the system can exhibit single-mode emission, wide bistability domains, and self-pulsing. The latter is often characterized by two frequencies, which are clearly related to single-mode and multimode instabilities, in agreement with the ...

Thermal radiation has a great effect on personnel evacuation when the train is on fire in the rack railway tunnels. However, the influence of the longitudinal slope, especially the large longitudinal slope, is not clear.

Propagation of guided waves in a hollow circular cylinder application to non destructive testing
In this paper, we study the propagation of guided waves in a tube and their interaction with surface defects. Axisymmetric (longitudinal and torsional) modes and nonaxisymmetric (flexural) modes are found and represented in phase and group velocity ...

Design of a Novel Type Micro-Stirrer Excited by Longitudinal Elastic Wave for Thrombus Dissolution
This paper presents the method to design a novel micro stirrer for high effective dissolution of cerebral thrombus or blood clot. The micro stirrer is a beam with supported one side and the other side is attached to an asymmetrical stirrer.

Intelligent Bus Platoon Lateral and Longitudinal Control Method Based on Finite-Time Sliding Mode
Considering the rapid convergence of the longitudinal and lateral tracking errors of the platoon, a finite-time tracking control method for the longitudinal and lateral directions of the intelligent bus platoon is proposed. Based on the bus platoon model

Single-Longitudinal-Mode Laser at 1123 nm Based on a Twisted-Mode Cavity
A single-longitudinal-mode (SLM) Neodymiun-doped Yttrium Aluminium Garnet (Nd:YAG) laser at 1123 nm was first demonstrated with a twisted-mode (TM) cavity. By eliminating the spatial hole burning phenomenon, a stable SLM 1123 nm laser output was obtained.

Beam halo studies using a three-dimensional particle-core model
In this paper we present a study of beam halo based on a three-dimensional particle-core model of an ellipsoidal bunched beam in a constant focusing channel including the effects of nonlinear rf focusing.
