Schematic Symbol For Laser
When used within a circuit they are often denoted as being a laser diode to distinguish them from other forms of light emitting diode.
Schematic symbol for laser. Laser diode the laser diode is similar to light emitting diode. But the light produced by laser diode produces coherent light laser beam. Each section is described in detail below. It is used in optical communication laser pointer cd drives and laser printer etc.
The laser diode symbol used in the circuit scheme is as shown above. The block diagram in figure 1 shows a very basic laser diode driver or sometimes known as a laser diode power supply. The diode is a semiconductor device that allows the current to flow in one direction only. This laser diode circuit symbol uses the basic semiconductor diode symbol with arrows indicating the generation and emanation of light.
Laser diode drivers vary widely in feature set and performance. It has two electrodes called anode or plate and cathode it uses the rectifying properties of the union between type p and n materials of a semiconductor. Laser diode just like led it converts electrical energy into light energy. The active region is formed in intrinsic region in pin structure.
Laser diodes find its applications in laser printing laser scanning etc. Each symbol is defined in the table below. Sometimes equipped with a circle around the diode.
