A bit too complicated to describe here, see the following for lots of detail. http://en.wikipedia.org/wiki/Diode
No. A diode laser is a semiconductor and Nd:YAG is a crystal.
p-type semiconductor is obtained by carrying out a process of doping that is by adding a certain type of atoms to the semiconductor in order to increase the number of the free charge carriers.
LASER is Light amplification by stimulated emission of radiation. As far as I have understood, Solid State laser is a macroscopic form of diode laser. Thus a small semiconductor diode is similar to a solid state laser except for the mechanism of lasing and size.
A PN Junction Diode is one of the least complex Semiconductor Devices around, and which has the normal for passing current in one and only heading just. Be that as it may, dissimilar to a resistor, a diode does not carry on directly regarding the connected voltage as the diode has an exponential current-voltage ( I-V ) relationship and thusly we can not portrayed its operation by just utilizing a comparison. ex: Ohm's law.

Diode is made of P and N type semiconductors having PN junction. The question is meanigless.
A Shockley diode uses a metal-semiconductor junction instead of a p-n semiconductor-semiconductor junction. This results in a device with a much lower forward bias voltage drop and much faster switching times.

An electronic component composed of two layers of a semiconductor material is a diode.
The 1 stands for number of semiconductor junctions The N means it's a semiconductor diode
