Fanout periodic poling of BaMgF4 crystals

The angle-dependent poling properties of 0.5-mm-thick BaMgF4 (BMF) crystals are investigated by means of calligraphically poled, radially oriented domains. We present a fanout periodic poling pattern for quasi-phase matching (QPM) applications, which covers an angular spectrum of about 14°. Within t...

Description
Summary:The angle-dependent poling properties of 0.5-mm-thick BaMgF4 (BMF) crystals are investigated by means of calligraphically poled, radially oriented domains. We present a fanout periodic poling pattern for quasi-phase matching (QPM) applications, which covers an angular spectrum of about 14°. Within this range there is no angle-dependent degradation of the domain quality. This is the first realization of non-parallel domains for QPM in BMF-crystals.
