Describe the construction of Neodymium-Yttrium-Aluminium-Garnet Laser.
Nd-YAG Laser
The one of the illustration for solid state lasers is Neodymium-Yttrium-Aluminium-Garnet Laser. This is an abbreviation of Nd: YAG Laser and is a four level system in that the active medium is taken into the form of a crystal. The construction of this laser is as demonstrated below:
Assume that two linked pistons are both cylindrical in shape. Show that the ratio of forces generated is directly proportional to the square of the radii of the two cross-sect
concept of position and displacement
Hooke's law (R. Hooke): The stress applied on any solid is proportional to the strain it generates in the elastic limit for that solid. The constant of that proportionality is
Energy gap: 1.4ev at room temperature Its charactistics are very closely related to those of germanium. This is under stable, since Gallium is the third column neighbour and a
ELECTROMOTIVE FORCE – EMF: To make use of electricity by provision of an electric current, the potential different must be maintained. That is, the positive and negative charg
