Abstract
In this paper, we present a compact size polarization-independent reflection-type potassium tantalate niobate (KTN) beam deflector, including (1) a single KTN crystal, (2) a quarter-wave plate, and (3) a retroreflector. Unlike the previously reported two KTN crystal based transmission-type polarization-independent deflector, our proposed deflector offers the advantage of compact size because only a single KTN crystal is needed. Furthermore, the reflection architecture allows more surfaces of the deflector to be cooled, enhancing the laser power handling capability and the deflection speed of continuous scanning. The experimental results were consistent with the theoretical model. Our proposed beam deflector can be beneficial for a variety of applications such as high speed, high resolution 2D/3D scanning, printings, and displays.
