We present a dual-crystal Yb:Lu2O3 laser in CW and cavity-dumped regime. We obtained 19.5 W CW output power in a diffraction limited beam. When cavity-dumped, the output energy was limited to 3 mJ, owing to surface da...

Monolithic active pixel detectors fabricated in SOI (Silicon On Insulator) technology are novel sensors of ionizing radiation, which exploit SOI substrates for the integration of readout electronics and a pixel detector. The fully depleted sensing diode has been manufactured under buried oxide (BOX) while read-out circuitry occupies upper silicon layer (‘device layer’). The development of the SOI detectors of ionizing radiation was started as a part of the SUCIMA project. During the project, it was proved that a monolithic SOI detector is a viable option for high-energy physics and medicine. The early prototypes suffered from significant leakage currents and soft breakdowns. These effects limited yield of production. Moreover, the p-wells (formed within the device layer and extended to the interface with the BOX), caused some local potential wells below the BOX at the top of depleted sensor area reducing the effective charge collection efficiency. The use a thicker device layer and optimized technology appeared to be a remedy.
We have demonstrated robust and efficient Kerr-lens mode-locked operation of a lowcost, diode-pumped Cr:LiSAF laser using a gain-matched output coupler. Sub-30-fs pulses with 80-pJ pulse energy have been demonstrated ...

A general-purpose frame-work is proposed to explore the potentials of a lateral p-n junction. Based on the motivation, we have augmented the existing knowledge with some new ideas to develop the said frame-work with a view to compute the resistance characteristics of a lateral GPNJ. The results obtained from our formulation are not only supported by experimental trends but also by other theoretical findings.

De novo prediction of protein structures, structures prediction from amino acid sequences which are not similar to those of hitherto resolved structures, has been one of the major challenges in bioinformatics. A new prediction protein structure method based on Genetic Algorithm and Coarse-grained protein model is presented. Genetic Algorithm is a high performance optimization method and can effectively assemble a separate sequence, and Coarse-grained protein model have consistently assembled fragments are dynamically searched by Langevin molecular dynamics of conformational change. This new method combines the advantages of Genetic Algorithm and Coarse-grained protein model, which will improve the accuracy of protein structure prediction.
We present HHG driven with a sub-cycle, mJ-level parametric waveform synthesizer. The variation of the HHG spectral shape and yield as a function of the relative phase between the synthesizer channels is shown. Photoe...
