We have developed simple and inexpensive laser systems
using grating-feedback diode lasers with electronic feedback to the
injection current. These grating-feedback lasers can be
continuously scanned up to 10 GHz and have a linewidth of 150 kHz.
The three electronic frequency-stabilization systems we developed
use polarization spectroscopy, etalon transmission and...
Worldwide, many organizations are pursuing higher energy efficiency by reducing power consumption of their processes, systems, and supporting infrastructure. The rapid growth of the information technology (IT) industry and the miniaturization of semiconductors have resulted in substantial increases in energy consumption and power density of IT equipment, and, subsequently, heat...
The need for clean and renewable fuel such as hydrogen is driven by a growing worldwide population and increasing air pollution from fossil fuels. One of the major barriers for the use of hydrogen in automotive industry is the storage of hydrogen. Physisorption is the most promising storage technique due...
