GaF 3-SrF 2-PbF 2-LiF-YF 3-LaF 3-NaF fluoroindate glass fibre is demonstrated for the first …

A polarization-independent ultra-broadband T-type absorber with doped silicon in the
terahertz band is proposed, which consists of T-shaped Si/SiO 2 arrays. The results show …

In the field of pulsed fiber laser, graphene is a well-known two-dimensional (2D) material for
its excellent optical properties. An alternative approach to the existing method, graphene …

We report an approach for high-resolution spectroscopy using a widely tunable laser
emitting in the molecular fingerprint region. The laser is based on difference-frequency …

Nanocrystal-in-glass composites (NGCs), comprising custom-tailored nanocrystals (NCs)
embedded in a transparent glass matrix, have recently attracted more attention due to their …

Bubbles generated with lasers in liquids under confinement have been investigated for their
potential use as the driving mechanism for liquid micro-jets in various microfluidic devices …

2 μm pulsed lasers not only have critical applications in military, medical, and processing
fields but are also an important frontier in laser physics. The development of these pulsed …

Improving the beam quality is the constant pursuit of the coherent beam combining (CBC),
and CBC is developing toward a large number of elements. In this work, we employed the …

Dy3+-doped fluoride fiber lasers have important applications in environment monitoring, real-
time sensing, and polymer processing. At present, achieving a high-efficiency and high …

Despite its widespread use in laser lithotripsy, the Ho: YAG solid-state laser suffers from
limited parameter combinations, poor beam quality, and low photoelectric conversion …
