The power supply of laser equipment is an important component of laser equipment, and its main function is to provide the required electrical energy for the laser. Before understanding the working principle of laser equipment power supply, there are several concepts that need to be understood first.

Laser working principle: A laser is a device that uses the harmonious vibration of light to generate high-energy light. It excites atoms or molecules in the laser medium to a high energy level through the interaction between the laser medium and the excitation device, and then generates coherent laser through the process of stimulated radiation.

Laser excitation device: The excitation device of the laser mainly refers to the energy pump used by the laser. Common excitation methods include photoelectron excitation, electron beam excitation, electron beam excitation, optical pumping, etc.

Working principle of laser equipment power supply:

1. Power input: The power supply of laser equipment usually needs to be connected to an external power source, such as an AC or DC power supply. In general, the power supply of laser equipment is converted into the DC power supply required for the laser by rectifying, filtering, and other processes on the external power supply.

2. Power regulation: The laser requires a certain amount of power to start and operate normally. The laser equipment power supply will adjust the output power according to the needs of the laser. In general, the power supply of laser equipment adjusts its output power through methods such as voltage, current, or pulse width.

3. Power protection: The laser equipment power supply needs to provide stable and reliable electrical energy for the laser. Therefore, the power supply of laser equipment usually has protective functions such as overcurrent, overvoltage, and overheating. When the laser equipment power detects that the current, voltage, or temperature exceeds the preset threshold, it will automatically cut off the power output to prevent device damage.

4. Isolation and filtering: The power supply of laser equipment usually requires isolation of interference between the laser and its sensitive components and external power sources to prevent interference from affecting the laser. At the same time, the laser equipment power supply also needs to filter out noise and interference in the power supply to ensure the stability and accuracy of the laser output.

In summary, the working principles of laser equipment power supply mainly include power input, power regulation, power protection, isolation and filtering, etc. Through these working principles, the laser equipment power supply can provide the required electrical energy for the laser, ensure its normal operation, and protect the laser from external interference and damage.
