For a limited time, find answers and explanations to over 1.2 million textbook exercises for FREE! Lasers are being used frequently in medical practice. This preview shows page 1 - 9 out of 54 pages. l. Similar to the HeNe-laser the Argon ion gas laser is pumped by electric dis­ charge and emitts light at wavelength: 488.0nm,514.5nm,351nm,465.8nm, 472.7nm, 528.7nm.It is used in applications ranging from retinal photother­ apy for diabetes, lithography, and pumping of other lasers. Course Hero is not sponsored or endorsed by any college or university. and an X-ray free-electron laser is shown in Table 1. Application ategoriesc. • Continuous power outputs up to 25 kW are obtainable hence this laser is the favoured choice for materials-processing applications such as cutting, welding and annealing.

Laser is an optical device that generates intense beam of coherent monochromatic light by stimulated emission of radiation.. Laser light is different from an ordinary light. • Unlike most other gas lasers, the CO 2 has an appreciably high efficiency typically 10 to 15 %. DEFINITION It is an intense beam of coherent monochromatic light (or other electromagnetic radiation) by stimulated emission of photons from excited atoms or molecules light amplification by stimulated emission of radiation. # The liver and lung diseases could be treated using lasers. • To reach the high powers required from these lasers, cavity lengths referred to as laser. Medical Laser… 2 laser and the CO laser and could build the first high-powerful lasers. every physician should know the mechanism of action and indications and different types of lasers used in medical practice. Laser safety potentially dangerous Class I/1 is inherently safe, light is contained in an enclosure, for example in cd players. APPLICATIONS Because of the high power levels available (combined with reasonable cost for the laser), CO2 lasers are frequently used in industrial applications for cutting and welding, while lower power level lasers are used for engraving. contents • Introduction • Electromagnetic radiation • Various terms • Absorption spectroscopy • UV/visible spectroscopy • Applications 3.
