  • Laser Diode Electroplating Principle

    Laser Diode Electroplating Principle

    A laser diode is electrically a. The active region of the laser diode is in the intrinsic (I) region, and the carriers (electrons and holes) are pumped into that region from the N and P regions respectively. While initial diode laser research was conducted on simple P–N diodes, all modern lasers use the double-hetero-structure implementation, where the carriers and the photons are confined in order to maximiz.


  • Low-voltage equipment relay protection principle

    Low-voltage equipment relay protection principle

    The principle is to grade the operating times of the relays in such a way that the relay closest to the fault spot operates first. Protective relays and devices have been developed over 100 years ago to provide “lastline”of defense for the electrical systems. The selection and applications of. The objective of this presentation is to convey a basic understanding of protective relays to an audience of engineers already familiar with low voltage protective device coordination.
