Journal ArticleDOI
High speed non-mechanical two-dimensional KTN beam deflector enabled by space charge and temperature gradient deflection.
Ju Hung Chao,Wenbin Zhu,Chang Jiang Chen,Adrian L. Campbell,Michael Henry,Shizhuo Yin,Robert C. Hoffman +6 more
TL;DR: This work provides an effective way for realizing multi-dimensional high-speed non-mechanical beam deflection, which can be very useful for a variety of applications, including high- speed 3D laser printing, high resolution high speed scanning imaging, and free space reconfigurable laser communications.
Journal ArticleDOI
New functionalities of potassium tantalate niobate deflectors enabled by the coexistence of pre-injected space charge and composition gradient
Wenbin Zhu,Ju Hung Chao,Chang Jiang Chen,Adrian L. Campbell,Michael Henry,Stuart Yin,Robert C. Hoffman +6 more
TL;DR: In this article, a high-resolution high-speed multi-dimensional K tantalate niobate (KTN) deflector was developed for 3D printing and in vivo imaging, where the authors studied the deflection behavior of KTN deflectors in the case of coexisting pre-injected space charge and composition gradient.
Proceedings ArticleDOI
Nanosecond KTN varifocal lens without electric field induced phase transition
Wenbin Zhu,Ju Hung Chao,Chang Jiang Chen,Adrian L. Campbell,Michael Henry,Stuart Yin,Robert C. Hoffman +6 more
TL;DR: In this article, the tuning principle of the KTN varifocal lens is based on the high-speed refractive index modulation from the nanosecond speed tunable electric field.
Proceedings ArticleDOI
A large capacity time division multiplexed (TDM) laser beam combining technique enabled by nanosecond speed KTN deflector
Stuart Yin,Ju Hung Chao,Wenbin Zhu,Chang Jiang Chen,Adrian L. Campbell,Michael Henry,Mark Dubinskiy,Robert C. Hoffman +7 more
TL;DR: In this article, the authors presented a novel large capacity (a 1000+ channel) time division multiplexing (TDM) laser beam combining technique by harnessing a state-of-the-art nanosecond speed potassium tantalate niobate (KTN) electro-optic (EO) beam deflector as the TDM multiplexer.
