Traditionally, brighter high harmonic generation (HHG) is achieved through continuously shifting driving laser to longer wavelength for higher ponderomotive energy and better phase matching. However, such approach has become less effective recently due to the challenge on generating high power MIR laser and the decreasing of HHG energy conversion efficiency. A novel study shows that DUV laser may be an alternative and more sustainable candidate for bright HHG. Intense DUV laser is used to generate effective phase-matching in multiply ionized plasmas, which require high average power, high pulse energy and ultrashort pulse duration simultaneously. This work presents the experimental development progress in our lab on high power DUV laser at 258 nm produced from ps Yb: YAG laser and ionization-induced self-compression of GW ultrashort pulses to tens of fs in gas. Furthermore, combining above two techniques and generating bright high harmonics in capillary filled with noble gas will be discussed.

We develop an optimization model to linearize analog photonic links (APLs) with substantially enhanced multi-octave spurious-free dynamic range (SFDR). By quantifying the power weighting factor and polarization incident angle, the link linearity is maximized at the optimal point.

We studied the precipitation process of silver nanoparticles (NPs) in the micron-sized waveguides laser-written in silver-containing phosphate glass. At the elaborated laser-writing regime and controllable writing speed, it is possible to tune the position and shape of the surface plasmon resonance band which reflects the change in the shape of the silver NPs from spherical to spheroidal. The proposed approach can be applied to control the anisotropy of the glass-metal composite materials.

Organic light emitting devices (OLEDs) are often manufactured and studied where the common point of interest is the characteristic current-voltage curve. Apart from the usual electron-hole recombination, inadvertently introduced, or not, “external" ions can induce unexpected effects. Among them are the "primary processes”, where the first forward bias scan is systematically very different from all subsequent ones. This curve shows two current “bumps” that disappear on all subsequent scans. The first bump is already explained in terms of ionic currents. This paper describes a different model in terms of the Cabrera-Mott oxidation process.
