Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
In this paper, we present a novel Brillouin fiber-ring laser utilizing an unbalanced Mach-Zehnder interferometer (UMZI) as coupling device. The laser is pumped by a distributed-feedback laser diode and shows continuous-wave and single-frequency operation. ...
WE examine the present state of holographic random access memory (HRAM) systems and address the primary challenges that face this technology, specifically size, speed, and cost. We show that a fast HRAM system can be implemented with a compact architecture ...
In order to improve the reliability of micro-spot welding of metal parts in production such as e.g. in electron guns for TV picture tubes, real-time information about the evolution of the welding process should be available to allow on-line modification of ...
We examine the primary challenges for building a practical and competitive holographic random access memory (HRAM) system, specifically for size, speed, and cost. We show that a fast HRAM system can be implemented with a compact architecture by incorporati ...

The properties of semiconductor laser diodes for trace gas measurements are reviewed. First, the modulation characteristics of these lasers are discussed. Then, two sensitive spectroscopic methods using a frequency-modulated near-IR laser are presented and ...
Nd:YAG laser welding of high reflectivity metals is difficult because of the highly non-linear light-material interaction yielding a narrow process window and poor reliability. However, achieving high reliability is mandatory for applying this technique in ...
The launch of molecules from liquid surfaces in a time of flight mass spectrometer has been investigated using different sample preparation techniques, and by exposing the liquid samples to two different laser wavelengths, 337 nm from a N2 ultraviolet lase ...
Modern lasers now routinely allow experiments where large populations of highly excited molecules can be prepared with perfect quantum state selection. In a sense, the laser has become the physical chemist’s synthetic tool, allowing “optical distillation” ...
We present a monolithically integrated coupled cavity vertical cavity surface emitting laser or BiVCSEL: this two-terminal electrically injected device exhibits stable laser emission at two design wavelengths simultaneously. The coupling between the two mo ...
We present the design of a highly efficient, pulsed ammonia laser which is optically pumped by a commercial TEA CO2 laser and is line tunable in the spectral range of 780-930 cm(-1). The power, spectral, and temporal characteristics of the laser have been ...
