Disc Geometry – Based Nd:Glass Laser

Abstract

Solid-state laser materials ordinarily consist of a transparent host material doped by active ions that replace some atoms or ions of the original material. These active ions contribute in stimulating laser action by the existence of energy levels relevant to spectra of absorption and emission. Specifically, neodymium glasses, which fluoresce at 1.06µm due to a transition from the 4F3/2 to the 4I11/2 state in the Nd3+ ion, have found interesting applications in the production and amplification of lasers used in laser fusion. The laser material interacts with the field incident on it and is pumped by one or more excitation sources (lamps or diode lasers). The pumping light may be directed towards the laser material from any direction relevant to laser radiation.The present work deals with the design, construction and characteristics study of solid state laser and Nd:glass, pumped with diode laser array at its end. A maximum power of 1 watt of 808 nm has been utilized to pump the Nd: glass disc of 2mm thickness and 12 mm diameter.
