We report development of a novel Tm3+ -doped fiber laser source at 1.86 μm based on highly nonlinear 55GeO2-45SiO2 dispersion shifted fiber, applicable to 3D-volume microprocessing of Si.

The simple and compact Tm-doped fiber MOPA generates tunable between 2-2.2 µm Raman solitons with average power up to 3W. Pulses as short as 130 fs and energy up to 38 nJ were demonstrated.

We report the first extended cavity Cr:ZnS chirped-pulse oscillator mode-locked by graphene. We demonstrate 415 mW average power at 8.6 MHz repetition rate which results in 48 nJ pulse energy.

In the aluminium industry today, smelters often have to rely on more than one alumina supplier. This creates diversity in the properties of smelter grade alumina (SGA). A method has been developed to compare the HF formation ...

Al-Mg-Si alloys often add small additions of e.g. Mn or Cr, to form dispersoids, which may act as nucleation sites for Mg2Si particles after homogenization. The purpose is to ensure a high density of uniformly distributed ...

We report supercontinuum generation in the range of 1.7-2.9 μm at up to 3.08 W of output power from a Tm-doped pulsed fiber laser emitting between 1.9-2.5 μm, spliced with a nonlinear fluoride or germanate fiber.

Ontology-based integrated materials modelling for an active protective coating system design is presented and applied to a practical example. For this purpose, an ontological methodology implemented using the ProMo (Process ...

The photovoltaic (PV) industry is in rapid growth and a large supply of PV feedstock materials must be provided to maintain this growth. Since silicon is still the dominant material for the fabrication of solar cells, ...

We demonstrate a novel interferometeric setup for broad-band (>300nm) GVD measurements in short-length optical fibers in the mid-IR wavelength range using a superluminescent fiber source and investigate specialty fibers ...
