Modeling of Q-switched lasers with top-hat pump beam distribution
For laser diode end-pumped solid-state lasers, the pump beam can be considered to be a Gaussian distribution or a top-hat distribution or between them. The rate equations for Q-switched lasers have…

An in-depth analysis of the Kerr effect in resonator fiber optic gyros (R-FOGs) based on triangular wave phase modulation shows that the measurement error for an R-FOG with a hollow-core photonic bandgap fiber as the fiber loop can be one to two orders of magnitude smaller than a conventional single mode fiber loop.
Two-dimensional grating coupler on silicon with a high coupling efficiency and a low polarization-dependent loss.
A two-dimensional grating coupler structure with a high coupling efficiency and a low polarization dependent loss is demonstrated, and the proposed configuration for the metal mirror facilitates a robust wafer-scale post-processing as well as an easy fiber alignment.
Controlled optical bistability switching in a diode-pumped Tm,Ho:LLF laser
We report on the experimental demonstration of stable all-optical switching between two steady state values of optical bistability from a laser diode end-pumped quasi-three-level Tm,Ho:LLF laser in…
Multi-wavelength fiber source with equal frequency spacing
A optical filter based on Sagnac interferometer was proposed to be acted as a comb filter with equal frequency spacing and good signal to noise ratio (SNR), which was composed of an 8.14 m…
Intrinsic bistability effect of Yb-sensitized Tm upconversion emission in zirconium dioxide nanocrystal
Intrinsic bistability in active optical compounds doped with rare-earth ions has attracted widespread interest because of its relevance for optical signal switching and routing. In this paper, room…
