The resonant pumping of holmium fibre lasers provides a fibre laser platform capable of addressing a wide range of applications that benefit from operation at wavelengths beyond 2.1 μm. This architecture can provide laser devices that promise high efficiency sources in the 2.1 μm spectral region with excellent beam quality and power scalability. This paper presents our recent results of resonan...

We give a review about the historical development and various technological achievements in the field of excimer lasers since their discovery in 1970. The first commercial excimer laser model in the world, the EMG 500 from Lambda Physik was operating at maximum repetition rates of only 20Hz, whereas today multi kiloHz excimer lasers as the NovaLine lasers are available. In 2000 Lambda Physik in...

In recent years, great attention has been paid to high peak power all-solid-state pulsed blue-green lasers [1–4] for some applications such as spectroscopy, display, optical data storage, coherent telecommunications, remote sensing, medicine, etc. Such lasers are generally realized by intracavity or external cavity frequency doubling of cw laser-diode (LD)-pumped solid-state Q-switched Nd-doped...

A register that is designed to allow the bits of its contents to be moved to left or right is known to be a shift register. Shift registers may be implemented by using pulsed latches and flip flops.However,shift register implemented by pulsed latches have power and area problems .So, flip flops are preferred over pulsed latches. In this paper, a VLSI architecture for low power area efficient VL...

The goal of the LAGUNA experimental series of the Los Alamos National Laboratory TRAILMASTER program is to accelerate an annular aluminum plasma z-pinch to greater than one hundred kilojoules of implosion kinetic energy. To accomplish this, an electrical pulse )5.5 MA must be delivered to a 20 nH load in ~1 ~s. The pulsed power system for these experiments consists of a capacitor bank for initi...

The goal of this paper is to propose a performance assessment for normally closed-loop type distribution power systems. Pilot relaying systems have been successfully applied to the protection scheme for normally closed-loop distribution systems in the Taiwan Power Company (Taipower). This paper demonstrates that the proposed protection scheme is extremely well designed, such that both the numbe...

The IT equipment comprising the Internet in the USA uses about $6 billion of electricity every year. Much of this electricity use is wasted on idle, but fully powered-up, desktop PCs and network links. We show how to recover a large portion of the wasted electricity with improved power management methods that are focused on network issues.

In this paper, a model of a railxun is developed and ~ used to illustrate a d&harge event on an energy storage capacitor. This rallgun model is designed to operate at a power level compatible with the Naval Combat Survivability testbed. The rallgun simulation model is Incorporated Into the NCS pulsed power charging circuit models. Simulations are perfonned showing the charglnx circuits charging...

HIGHLIGHTS Single-switch configuration for the proposed hybrid converter is employed. Static voltage gain of topology improved. Power switch subjected to low voltage-current stress. The power conversion efficiency

Abstract Anisakis is a parasite that found in many marine products and can cause anisakiasis when present fish consumed raw. The most common way to prevent freeze the fish, but this causes noticeable decrease quality of eaten as sashimi. Although no practical method killing anisakis other than freezing has been found, we have now succeeded inactivating inside meat by repeatedly instantaneously ...
