what are solid state lasers used for

The original laser invented in 1960 was a solid state laser. The SSLTE will be used to evaluate the capability of a 100kW-class solid-state laser to accomplish a variety of missions. In these lasers, glass or crystalline materials are used. Optical pumping is a relatively low power method and the whole point to the complications of gaseous lasers is to go to high power, so even if it could be applied to gas laser, optical pumping would deliver low power transfer. Following the host and the ions used, the emission spectra can be narrow (fraction of nm) or wide (undredth of nm). The process of adding impurities to the substance is called doping. Solid State lasers : They are high power lasers and used for industrial applications such as welding, drilling, cutting, molding etc. Laser Components and Accessories power to change the diffraction efficiency. The company has a lead role in integrating and operating the Army's solid-state laser … In general, solid state lasers emit in the red and near infrared. It used a synthetic ruby rod (chromium doped aluminum oxide) with mirrors on both ends (one semitransparent) pumped with a helical xenon flashlamp surrounding the rod. The gain medium of a solid-state laser consists of a glass or crystalline "host" material. Ions are introduced as impurities into host material which can be a glass or crystalline. A solid-state laser is a laser that uses solid as a laser medium. The damage often takes the form of voids within the rod or pits on the ends of the rod. Because that is what works - chemical pumping could not be used on solid state because they are solid - chemicals can't get in. Some can cut through metal, while others read tiny bits of … 176 5. The lamp was similar to what is used for indoor and high speed photography. But there is another important class of solid-state lasers — vibronic lasers — that emit light with a wider range of frequencies. All of the solid-state lasers mentioned so far emit light at relatively discrete wavelengths, such as 694.3 nm for ruby or 1.064 µm for Nd:YAG. Usually all solid state lasers are pumped optically means light source is used as energy source of solid state lasers. Two common solid state lasers used today are Nd:YAG (neodymium:yttrium aluminum garnet) and Nd:glass. A solid-state laser is a laser that uses a gain medium that is a solid, rather than a liquid as used in dye lasers or the gas that's in a gas laser. Types of Lasers There are many types of lasers available for research, medical, industrial, and commercial uses. There are many host materials in which laser excitation has been achieved, but relatively few types are in widespread use. When one uses an acoustooptic device as a deflector, one keeps the acoustic power constant but varies the … - Selection from Industrial Applications of Lasers, 2nd Edition [Book] Lasers are often described by the kind of lasing medium they use - solid state, gas, excimer, dye, or semiconductor. We know that active medium used for solid state lasers is a solid material. Of particular interest is the wavelength of Nd 3+ :YAG(Y 3 Al 5 O 12 ) with an emission at 1064 nm. It is this application that generates the most serious problems of laser damage. When the solid material rod absorbs the light energy from light source then becomes excited. Solid state lasers use high density solid media as active laser materials. The laser rods in solid state lasers can be damaged by the high light intensity. Lasers are used in practically every major industry, from medicine and computers to entertainment and construction. The first solid-state laser used a rod of pink ruby and an artificial crystal of sapphire. A power rating, usually in watts, determines the strength of the laser. Solid state lasers have lasing material distributed in a solid matrix, e.g., the ruby or neodymium-YAG (yttrium aluminum garnet) lasers. Those results will be the basis for directing future development of solid-state lasers as a weapon system. Both use krypton or xenon flash lamps for optical pumping. Solid state lasers like Nd:glass are often used for generation of short, high-power pulses. These applications require very high power with peak value in kilowatts to megawatts.
