概要

• 論文の詳細を見る

• A dual-layer volume holographic optical element is proposed as a beam-splitting element for a three-wavelength(λ=0.4μm, 0.65μm and 0.8μm)optical disk pickup.We fabricated it for normal incidence using photopolymer film via an inexpensive laminate process.It is demonstrated that it exhibited excellent wavelength selectivity(extinction ratio ≥ 〜100)with a high diffraction efficiency of 99.7%.This element could be a key device in a next-generation multi wavelength optical disk pickup.
