We report an efficient diode-pumped high-power cryogenic regenerative amplifier operating at 1019 nm employing the c axis of Yb:YLF. Compared to usually selected 1017 transition a axis, c-axis line has three-fold higher emission cross section and still possesses full-width half-maximum (FWHM) 6.5 125 K. The chirped-pulse system is seeded by fiber front-end with energy 30 nJ stretched pulse widt...

The Milner-Damas typing algorithm W is one of the classic algorithms in Computer Science. In this paper we describe a formalised soundness and completeness proof for this algorithm. Our formalisation is based on names for both term and type variables, and is carried out in Isabelle/HOL using the Nominal Datatype Package. It turns out that in our formalisation we have to deal with a number of is...

A catalytic sensor for the measurement of radical density in weakly ionized CO(2) plasmas, created in a low-pressure electrodeless discharge, is presented. The CO(2) plasma was created in a 4 cm wide borosilicate glass tube inside a copper coil connected to a radio frequency generator operating at 27.12 MHz with a nominal power of 250 W. The dissociation fraction of the CO(2) molecules was meas...

Robust performance controller design for duty-cycle controlled series resonant converter (SRC) is proposed in this paper. The uncertainties of the converter are analyzed with load variation and power circuit components tolerances are taken into consideration. Additionally, a nominal performance (NP) controller is designed. Closed-loop system is simulated with Orcad and simulation results of r...
