Application Cases

Experiment Name: The Application of the ATA-7020 High-Voltage Amplifier in the Study of Ferroelectric Domain Switching

Experiment Content:The ATA-7020 high-voltage amplifier is used to achieve domain switching in ferroelectric materials. In the field of nonlinear optics, improving frequency conversion efficiency is one of the key objectives. Traditional phase-matching methods are limited by the material's dispersion characteristics, while quasi-phase matching (QPM) technology compensates for phase mismatch by creating a periodic structure within the material, thereby enhancing frequency conversion efficiency. Particularly in crystals with ferroelectric properties, periodic domain switching can be achieved by applying a high electric field, realizing quasi-phase matching. In this process, the use of a high-voltage amplifier to apply a high electric field is a crucial step in achieving periodic domain switching.

Research Direction: Ferroelectric Materials

Testing Equipment:ATA-7020 high-voltage amplifier, signal generator, samples, etc.

Experimental Process:

By carefully designing and optimizing processing parameters, we can precisely apply a high-voltage electric field to the material surface. In this process, the use of a high-voltage amplifier is crucial. It not only provides the required high electric field strength but also allows precise control over the stability and uniformity of the electric field. Through this method, we can effectively create domain switching structures within ferroelectric crystals, achieving quasi-phase matching. The role of the high-voltage amplifier in this process is indispensable. It ensures the precise application of the electric field, enabling the material processing results to meet the expected high-efficiency standards.

Experimental Results:

In the processing of ferroelectric materials, we successfully achieved stable and high-quality domain switching through the carefully designed application of a high-voltage electric field. This outcome was made possible by using the high-voltage amplifier to provide a stable high-voltage electric field. The field is not only strong but also uniform and stable, ensuring the periodicity and consistency of domain switching. In the experiment, the boundaries of domain switching were precisely controlled, resulting in the formation of the expected domain structures and high-quality outcomes.
