Development, Features and Applications
industry, medicine and other areas of contemporary life. The essential ingredients of a laser are a material that amplifies light through stimulated emission (the gain medium) and a cavity that traps light in the gain medium to enable more efficient amplification. The gain medium is pumped electrically, by a source current, or optically, by another laser source or a lamp. The most common laser ...
متن کاملDevelopment and applications of compact high-intensity lasers
The development of compact high-intensity lasers, made possible by the technique of chirped pulse amplification, is reviewed. This includes the complexities of high-power laser implementation, such as the generation of short pulses, pulse cleaning, wide-bandwidth amplification, temporal stretching and compression, and the requirements for high-average powers. Details of specific solid-state las...
متن کاملLasers and their Applications
Ever since the advent of the first LASER (acronym for Light Amplification by Stimulation Emission of Radiation) in 1960, there has been a steady increase in the application of lasers. Applications have kept on becoming more and more diverse as the capability of the lasers have increased. In this chapter we will enumerate and classify many of the applications of lasers and then go on to discuss ...
متن کاملDomesticating random lasers
Random lasers are exotic light sources that emit coherent light without any of the confining mirrors that are part of a conventional laser.1, 2 Instead, the light inside a random laser is trapped by multiple scattering in a disordered medium and can thus be efficiently amplified. The downside is that random lasers emit their light at many different frequencies and in many different directions (...
متن کاملodes of random lasers
In conventional lasers, the optical cavity that confines the photons also determines essential characteristics of the lasing modes such as wavelength, emission pattern, directivity, and polarization. In random lasers, which do not have mirrors or a well-defined cavity, light is confined within the gain medium by means of multiple scattering. The sharp peaks in the emission spectra of semiconduc...
