Dispersion-managed Monolithic All Polarization-Maintaining Ultrafast Thulium-doped Fiber Oscillator [PDF]
EPJ Web of Conferences, 2022 We report on our first results of a dispersion-managed monolithic polarization-maintaining ultrafast Thulium-doped fiber oscillator. The design incorporates only commercially available polarization-maintaining components and emits linearly polarized ...

Communications Physics, 2021 AbstractTraditional lasers function using resonant cavities, in which the round-trip optical path is equal to an integer multiple of the intracavity wavelengths to constructively enhance the spontaneous emission rate. Taking advantage of the cavity enhancement effect, the narrowest sub-10-mHz-linewidth laser and a 10−16-fractional-frequency-stability ...

Thermo-optical wavefront distortions in Nd:YVO4 laser amplifiers [PDF]
EPJ Web of Conferences, 2022 The power dependence of a Nd:YVO4 laser amplifier beam wavefront was analyzed by Zernike polynomial decomposition. This analysis was performed experimentally and by simulations based on split-step Fourier propagation showing a good agreement.

Scientific Reports, 2015 AbstractCavity optomechanics explores the interaction between optical field and mechanical motion. So far, this interaction has relied on the detuning between a passive optical resonator and an external pump laser. Here, we report a new scheme with mutual coupling between a mechanical oscillator supporting the mirror of a laser and the optical field ...

High-stakes testing policy and English language teaching: Voices of the leftovers
Journal on English as a Foreign Language, 2020 High-stakes testing has been controversial in many countries for several impacts and reasons surrounding its implementation. Teachers’ voices should be heard for well-rounded education policy. This study aims to investigate the voices of English teachers
