An excessively tilted LPFG-assisted surface plasmon polaritons sensor (ExTLPFG assisted SPP sensor) with ultrahigh sensitivity is proposed and numerically investigated using the finite-element-method-based full-vector complex coupled mode theory. We

A compact KTA cascaded Raman system driven by a passively Q-switched Nd:YAG/Cr4+:YAG laser at 1064 nm was demonstrated for the first time. The output spectra with different cavity lengths were measured. Two strong lines with similar intensity were ac

An acousto-optic Q-switched self-Raman laser emitting around 1.2-1.3 μm based on cascaded conversion with the Raman shifts of 259 and 890 cm-1 was demonstrated in a c-cut Nd:YVO4 crystal. The laser starts with single Stokes emission at 1215 nm. As t

We have demonstrated an efficient diode-end-pumped continuous-wave Tm:YAG ceramic laser at 1962 nm using a compact two-mirror cavity. The laser oscillation at 1962 nm was realized by increasing the cavity loss at 2016 nm to limit oscillation with the

The pulse widening in fiber communications causes a significant restriction of bit rate. The intermodal dispersion occurs not only in grade-index multimode fibers but also in the two-core single-mode fiber. The Goos–Hänchen (GH) shift is not consi

In this paper, we demonstrated a continuous-wave intracavity singly resonant optical parametric oscillator based on periodically poled MgO:LiNbO3 (MgO:PPLN) pumped by a diode-pumped Nd:YVO4 laser at 1064 nm. The singly resonant optical parametric osc

Nanoscale nipple array (NNA) structures have always been used in solar cells for the purpose of antireflection. However, most NNAs are fabricated on the planar surface of a film. Here, we report NNA structures are fabricated on the curved surface of
