Excimer Lasers in Medicine
Introduction Excimer lasers emit light energy, short optical pulses at ultraviolet wavelengths, that results in a unique laser tissue interaction. This has led to an increasing number of studies into medical applications of these lasers in fields such as ophthalmology, urology, cardiology and neurology. The typical excimer laser is operated with a combination of a halogen (fluorine or chlorine)...
متن کاملDeep-UV Excimer Lasers
The recent trend in microelectronics towards patterning critical feature sizes of 0.25 m and below has motivated the development of microlithography at the deep ultra-violet (DUV) laser wavelengths of 248 and 1 93 nm. In recent years the performance, reliability, and cost of ownership of excimer light sources have improved. Some key technologies needed for excimer lasers in microlithography inc...
متن کاملPicosecond and sub-picosecond pulse generation in semiconductor lasers
Generation of short optical pulses in semiconductor lasers is of practical interest for an increasing number of applications. It is also of fundamental interest because of its tight relation with the field of semiconductor laser dynamics. After an introductory review, we compare the performances of gain-switching, Q-switching and mode-locking techniques. The comparison is illustrated by experim...
متن کاملMiniaturized Cutting and Drilling Using Picosecond Lasers Sidebar: Using Picosecond Lasers to Produce Disposable Ophthalmic Blades
Traditionally, electrical discharge machining (EDM) or conventional laser tools have been used to manufacture a range of precision medical devices. However, these manufacturing methods cannot be used to achieve the miniature features, precision, surface quality, and yields required for manufacturing microfluidic devices for clinical lab-on-a-chip applications, precision drug-delivery catheters,...
متن کاملExcimer lasers—40 never looked better
The first commercial excimer laser was introduced 40 years ago by Lambda Physik (now Coherent; Santa Clara, CA). Interestingly, its developers— Bernd Steyer and Dirk Basting—were both chemists whose main goal was to develop a light source for photochemistry and dye laser pumping. As soon as excimer lasers entered the market, Lambda Physik began to investigate other possible uses for a powerful ...
