What is the practicability of laser power supply?

The laser power supply is equipped with manual light output test button, which is convenient for detection and maintenance. With status indicator, it is easy to judge the fault. It has the function of open circuit protection, which can significantly prolong the service life of the power supply. The high-voltage line is connected to the high-voltage end of the laser tube; the low-voltage line is connected to the optical end of the laser tube (if it is connected to the ammeter, it is connected in series on the low-voltage line). It has small volume, stable performance, and the cooling capacity is up to 800W. So what is the practicability of laser power supply?

Different properties of the working particles emitted by the laser power supply can produce different energy.

The operation of the xenon lamp can be divided into three stages: ignition, preignition and high voltage discharge. Optical pump type laser accessories.

It refers to laser accessories excited by optical pump, including almost all solid laser accessories and liquid laser accessories, as well as a few gas laser accessories and semiconductor laser accessories. Semiconductor laser accessories, which use certain semiconductor materials as working materials to generate stimulated emission.

The principle is to realize the inversion of the number of particles between the energy bands of semiconductor materials or between the energy bands and the impurity energy levels by certain excitation methods (electric injection, optical pumping or high-energy electron beam injection), so as to produce the laser emission.

Its working process is relatively complex, which is an unstable gas emission. In the ignition stage, the discharge first produces ionization channel near the trigger line on the inner wall of the quartz tube, the gas is heated due to the collision with electrons, the xenon in the lamp is rapidly ionized, and the glow discharge occurs.

In the pre ignition stage, when the input energy is large enough, the electrode is heated to a certain heat dissipation capacity, and the gas in the lamp transits from glow discharge to arc discharge.

In the stage of high voltage discharge, the pulse xenon lamp is arc discharge. During the high voltage discharge phase, the preignition circuit always supplies a holding current (about 100 mA) to the pulse xenon lamp.

In the traditional pre ignition system of pulse xenon lamp, voltage source is needed in ignition stage and pre ignition stage respectively.

Solid state laser accessories, that is, the working material used for such laser accessories, are made by doping metal ions that can produce stimulated radiation into crystal or glass matrix to form luminous centers.

Optically pumped laser accessories refer to laser accessories excited by optical pump, including almost all solid laser accessories and liquid laser accessories, as well as a few gas laser accessories and semiconductor laser accessories.

Pulse width modulation technology is used to control the ignition power supply of new type pulse xenon lamp. The ignition and pre ignition stages share one power supply.

Ignition is voltage source and pre ignition is constant current source. In the start-up phase, the maximum duty cycle outputs the maximum voltage, and the high voltage start-up voltage is obtained by series resonance.

In the precombustion stage, a constant current (about 100 mA) is output by adjusting the duty cycle.

The practicability of the above laser power supply is here for you. The use of laser power supply and different industrial fields have made great contributions to high-speed spindle, electrical shaft, grinder, machining center, laser marking machine, laser engraving machine and other industries. We usually don't know about it, but its use value is quite high.
