Abstract (AI)
A 1mm thick flux-grown KTiOPO4 sample was poled with a 720nm domain period by employing deep-UV laser lithography, chemical patterning, and electric field poling. An atomic force microscope was used to characterize the periodic domain structure. The sample was used to demonstrate sixth and seventh order quasi-phase-matched backward second-harmonic generation.
Key Findings
1
A 1 mm thick flux-grown KTiOPO4 (KTP) sample was successfully periodically poled with a 720 nm domain period.
2
Atomic force microscopy characterized and confirmed the fabricated periodic domain structure.
3
Deep-UV laser lithography, chemical patterning, and electric field poling were combined to produce submicrometer periodic domain structures in KTP.
4
The poled KTP sample demonstrated sixth- and seventh-order quasi-phase-matched backward second-harmonic generation.
