  • What is CO2 laser source?

    What is CO2 laser source?

    How does a CO2 Laser work? Modern CO2 machines usually produce the laser beam in a sealed glass tube which is filled with gas, usually carbon dioxide. A high voltage flows through the tube and reacts with the gas particles, increasing their energy, in turn producing light.

    Quite simply, it is referring to creating the laser beam by stimulating a gas mixture made up of helium (He), nitrogen (N2), hydrogen (H2), xenon (Xe) and carbon dioxide (CO2). A CO2 laser operates by stimulating the gas mixture with either direct current (DC) voltage or radio frequency (RF) waves.

  • zener diode

    zener diode

    A Zener diode is a special type of diode designed to reliably allow current to flow “backwards” when a certain set reverse voltage, known as the Zener voltage, is reached.

    Zener diodes are manufactured with a great variety of Zener voltages and some are even variable. Some Zener diodes have a sharp, highly doped p–n junction with a low Zener voltage, in which case the reverse conduction occurs due to electron quantum tunnelling in the short space between p and n regions − this is known as the Zener effect, after Clarence Zener. Diodes with a higher Zener voltage have a more gradual junction and their mode of operation also involves avalanche breakdown. Both breakdown types are present in Zener diodes with the Zener effect predominating at lower voltages and avalanche breakdown at higher voltages.

    Zener diodes are widely used in electronic equipment of all kinds and are one of the basic building blocks of electronic circuits. They are used to generate low-power stabilized supply rails from a higher voltage and to provide reference voltages for circuits, especially stabilized power supplies. They are also used to protect circuits from overvoltage, especially electrostatic discharge (ESD).

  • zener diode as voltage regulator

    Zener Diodes can be used to produce a stabilised voltage output with low ripple under varying load current conditions. By passing a small current through the diode from a voltage source, via a suitable current limiting resistor (RS), the zener diode will conduct sufficient current to maintain a voltage drop of Vout.

    How is Zener diode used as voltage regulator?

    When the Zener diode is given reverse bias feedback, there is a small leakage current until it attains the breakdown voltage or a constant voltage. At this point, the current begins flowing seamlessly without any change in voltage. Therefore, the constant voltage helps Zener Diode as Voltage Regulator.

  • 1n4148 diode direction

    The 1N4148 diode. The black band at one end of the 1N4148 diode indicates the cathode (negative side). Current flows from the anode (positive side) to the cathode, but not the other way. (Some types of diodes have a silver band instead of a black band to indicate the cathode.)

    how to identify 1n4148 diode

    The 1N4148 is the neat looking orange-and-black diode, where the black line marks the negative (cathode) side. The 1N4001 is the black and gray diode, and the gray line marks its cathode.

  • 1n4148 voltage drop

    This is a very common signal diode – 1N4148. Use this for signals up to 200mA of current. Very general purpose, it’s got a typical forward voltage drop of 0.72V and a 300mA maximum forward current rating.

    The voltage drop accross a diode is a non-linear function of current. It is not a fixed voltage source, but is around 600-700 mV for most normal currents.

    A regular 1N4148 silicon diode has a forward drop of about 0.65V, quite a bit when supplies are 2..3V!

    The Schottky diode has a much lower voltage drop. It’s usually specified as 0.3..0.4V, but it really depends on the amount of current passed through it.
