A review of fast speed solid state KTN beam deflectors
Shizhuo Yin

n this paper, we provide a brief review on fast speed solid state beam deflectors based on potassium titanalate niobate (KTN) electro-optic (EO) crystals. Different types of beam deflection mechanisms are addressed, including both the conventional uniform electric field but non-uniform geometric shape (e.g., prism shape) enabled beam deflection as well as non-conventional non-uniform electric field enabled beam deflection. The non-uniform electric field can be realized by several different approaches such as space-charge-controlled beam deflection, temperature gradient controlled beam deflection, and composition gradient controlled beam deflection. The advantages and limitations of each approach are discussed. Furthermore, we present the method of how to realize nanosecond speed, large aperture KTN beam deflection by overcoming the electric field induced phase transition. Finally, we discuss a variety of killer applications of fast speed solid state KTN beam deflectors, including high speed high resolution imaging and display, high speed 2D/3D printing, massive high speed optical storage, as well as all-solid state holographic systems.
