Analysis of ring laser gyroscopes including laser dynamics [PDF]
The European Physical Journal C, 2019 Inertial sensors stimulate very large interest, not only for their application but also for fundamental physics tests. Ring laser gyros, which measure angular rotation rate, are certainly among the most sensitive inertial sensors, with excellent dynamic ...

Dynamics of multisection semiconductor lasers
Mathematical Modelling and Analysis, 2004 We investigate the longitudinal dynamics of multisection semiconductor lasers based on a model, where a hyperbolic system of partial differential equations is nonlinearly coupled with a system of ordinary differential equations.

Evaluation of the relevance of melt pool dynamics in Laser Material Deposition process modeling
International Journal of Heat and Mass Transfer, 2017 The melt pool dynamics consideration in the numeric modeling of the Laser Material Deposition (LMD) process can be enormously difficult and expensive, especially if this calculation is not strictly necessary.

Period-One Laser Dynamics for Photonic Microwave Signal Generation and Applications
Photonics, 2022 Due to the advantages of rich dynamics, small size, and easy integration, semiconductor lasers have many applications in microwave photonics. With a proper perturbation to invoke period-one (P1) nonlinear laser dynamics, a widely tunable microwave signal

Attosecond magnetization dynamics in non-magnetic materials driven by intense femtosecond lasers
npj Computational Materials, 2023 Irradiating solids with ultrashort laser pulses is known to initiate femtosecond timescale magnetization dynamics. However, sub-femtosecond spin dynamics have not yet been observed or predicted.
