Efficient Optical to Microwave Conversion

IEEE Microwave Magazine, 2014
Modern-day communications often involve the use of specially designed fiber-optic channels as a guided wave propagation medium. Information is carried through this medium as a modulated light beam, which can then be received and utilized in a manner similar to traditional analog signaling.

Efficiency Regulations: Driving power conversion efficiency designs

IEEE Power Electronics Magazine, 2017
In recent decades, government agencies developed programs to improve the efficiency of our electronic products and appliances. A 1999 study estimated that up to 10% of electricity consumed by residential products was wasted when products had been turned off by consumers [1].

Conversion efficiency of catalytic converter

International Journal of Ambient Energy, 2015
Around 50 million vehicles are manufactured every year and over 700 million vehicles are used worldwide. Vehicle population is predictable to grow close to 1300 million by the year 2030. Automobile produced 10,037,168 short tons of nitrogen oxides and 59,383,083 short tons of carbon dioxide in 2008 alone.

Energy Efficiency and Conversion

Abstract:The increase demand of energy is due to advance technology and appliances. However, fossil fuel-sourced energy is harmful for environment. Green energy is an alternative to curbing the energy demand. Photovoltaic cells, hydro turbines, and fuel cells are the most efficient sources of green energy. Fuel cells have been modified to utilize fuels

Efficient up-conversion in CdSe

Optics Communications, 1976
Abstract In this work up-conversion in CdSe with a HF laser as a pump and an experimental quantum efficiency higher than 40% is reported. With this device, it is possible to obtain up-conversion in the 8–25 μ wavelength range.

LPP EUV conversion efficiency optimization

SPIE Proceedings, 2005
Efficient conversion of laser light into EUV radiation is one of the most important problems of the laser-produced plasma (LPP) EUV source. Too low a conversion efficiency (CE) increases the amount of power the drive laser will have to deliver, which, besides the obvious laser cost increase, also increases the thermal load on all the components and can

Conversion Efficiency of LPP Sources

2010
Some EUV light sources have been promoted that use LPPs, and some that use DPPs (see, for example, Ref. 1). Although each proposed source has significant advantages, the LPP offers an especially attractive prospective application range due to advances in laser technology and tunability of the source emission by target-material selection.

CONVERSION EFFICIENCIES IN HETEROTROPHIC ORGANISMS

Biological Reviews, 1977
Summary1. The maximum possible efficiency at which living systems are able to convert input nutrients to their own biomass is between 70 and 80 %.2. Conversion efficiency in bacteria, protozoa and metazoan cells in culture approximates more closely to 60%.3.
