High Quality Content by WIKIPEDIA articles An excimer laser (sometimes, and more correctly, called an exciplex laser) is a form of ultraviolet laser which is commonly used in eye surgery and semiconductor manufacturing. The term excimer is short for excited dimer, while exciplex is short for excited complex. An excimer laser typically uses a combination of an inert gas (argon, krypton, or xenon) and a reactive gas (fluorine or chlorine). Under the appropriate conditions of electrical stimulation, a pseudomolecule called an excimer (or in case of noble gas halides, exciplex) is created, which can only exist in an energized state and can give rise to laser light in the ultraviolet range. The UV light from an excimer laser is well absorbed by biological matter and organic compounds. Rather than burning or cutting material, the excimer laser adds enough energy to disrupt the molecular bonds of the surface tissue, which effectively disintegrates into the air in a tightly controlled manner through ablation rather than burning.

High Quality Content by WIKIPEDIA articles Quantum cascade lasers (QCLs) are semiconductor lasers that emit in the mid to farinfrared portion of the electromagnetic spectrum and were first demonstrated by Jerome Faist, Federico Capasso, Deborah Sivco, Carlo Sirtori, Albert Hutchinson, and Alfred Cho at Bell Laboratories in 1994. Unlike typical interband semiconductor lasers that emit electromagnetic radiation through the recombination of electronhole pairs across the material band gap, QCLs are unipolar and laser emission is achieved through the use of intersubband transitions in a repeated stack of semiconductor multiple quantum well heterostructures, an idea first proposed in the paper Possibility of amplification of electromagnetic waves in a semiconductor with a superlattice by R.F. Kazarinov and R.A. Suris in 1971. Author: Surhone, Lambert M./ Tennoe, Mariam T./ Henssonow, Susan F.

Chaotic semiconductor laser diodes can be used to precipitate secure communications schemes via synchronisation of two such lasers. This book begins by extending the bifurcation analysis of Dubbeldam and Krauskopf to dimensionless equations derived from the Yamada model with terms representative of spontaneous emission and diffusion effects included. We show that the bifurcation diagram changes dramatically at a certain diffusion level, but that the region of selfpulsation is still delineated by the Hopf bifurcation curve. Other models which include recombination effects are also considered. The excitable region of the parameter space of the dimensionless equations derived from the Yamada model with diffusion effects neglected is considered, and approximations of the excitability threshold are derived. Finally, chaotic behaviour arising from sinusoidal modulation of the pump current is analysed. Lyapunov exponent calculations are supplemented with a return map analysis in order to distinguish between periodic motion and chaos as the modulation depth and frequency are varied.

Miniaturization has long been a trend in the creation of better devices, and the study of alternative materials for the production of wellknown devices forms one large fraction of material science. Lasers and semiconductor devices have both had their part in the shaping of our current technological age and have formed a symbiosis in semiconductor lasers. The omnipresence of these unique light sources and the remaining high cost and ecological impact of growing suitable semiconductor materials have sparked the study of organic semiconductor devices and among them organic semiconductor lasers (OSLs). Still a field of great research efforts, the concept of microcavities as base structure for such systems holds the promise of inexpensive, organic or plastic semiconductor lasers available to the evergrowing markets of consumer electronics. Studied since the mid90s, first organic microcavity lasers had largely inaccessible dynamics until femtosecond spectroscopic techniques became increasingly available. This book presents a study of one exemplary system, its dynamics and coherent properties. Also, introductory chapters allow greater access to the field of organic microcavities.

In Laser Physics the interaction of radiation and matter, and the principles of laser operation are treated at a level suitable for fourth-year undergraduate courses or introductory graduate courses in physics, chemistry or engineering. The factors which determine efficiency, wavelength coverage, output power, and beam quality of the different classes of laser are treated both in terms of fundamental theory and practical construction aspects. Details of established types of solid-state, semiconductor, and gas lasers are examined together with the techniques that enable their output to be converted widely across the spectrum. The latest advances in high power fibre lasers, femtosecond lasers, and X-ray lasers are explained. The text is liberally illustrated with more than 300 diagrams. An extensive bibliography is provided, together with numerical problems in each chapter. Solutions are available via the web.

Semiconductor Laser - inventor Bob Hall
What are the properties of the semiconductor laser in Star Trek, The Next Generation?
Im not sure if the semiconductor is a laser but I think it is. So could someone please help me out???
I think semiconductors are a type of diode that allow light to be amplified by the stimulated emission of radiation. (LASER = Light Amplification via Stimulated Emission of Radiation) Thus, I would consider a semiconductor as a vehicle for the laser, rather than a specific type of laser light.
Naren Shankar, a writer and science consultant for Star Trek TNG, studied nuclear engineering at Cornell, where he actually built semiconductors. Naturally, this knowledge was used in the show. I've listed a good article about him in my sources if you're interested!
