LASERS BASICS 1. basic defintions of laser, fundamentals of laser, types of laser, He-Ne laser,merits and demerits of laser. >>Invented in 1958 by Charles Townes and Arthur Schawlow of Bell Laboratories >>Was based on Einstein’s idea of the “particle-wave duality”of light. Laser light is emitted has wavelength of 633 nm (red), power in the range 0.5 to 50 mW; beam divergence about 1 mrad. Regular) Optical discs, laser pointers, data communications. Lasers are commonly designated by the type of lasing. Let us understand basics of these different types of lasers. Clipping is a handy way to collect important slides you want to go back to later.

Lasers are classified into 4 types based on the type of laser medium used: Solid-state laser; Gas laser; Liquid laser; Semiconductor laser; Solid-state laser 3-level laser and 4-level laser. LASERS 2. You can change your ad preferences anytime. N 1 to achieve the condition of population inversion between E 2 and E 1 at moderate pumping. Laser can also be classified based on other parameters such as Gain of the laser medium, power delivered by laser, Efficiency or Applications of usage. >>LASER is an acronym for Light Amplification by Stimulated Emission of Radiation.
