    • An OPCPA apparatus of the present invention includes an optical pulse stretcher (100) for temporally stretching laser light, and applying short-wavelength preceding-type chirping. Pump lasers (210, 220) emit pump laser light. A first OPA unit (310) receives the pump laser light, and a signal having passed through the optical pulse stretcher, amplifies the signal, and generates a first idler. A first optical signal separation unit (410) separates output light of the first OPA unit into the first idler and remaining light (pump and signal). A second OPA unit (320) receives the first idler and another pump laser light, amplifies the first idler, and generates a second idler. A second optical signal separation unit (420) separates output light of the second optical parametric amplification unit into an amplified first idler and remaining light (pump and second idler). An optical pulse compressor (600) temporally compresses the amplified first idler.

    • Disclosed herein are a novel perfluoroalkyl vinyl ether compound, a process for preparing a copolymer by using the perfluoroalkyl vinyl ether compound, and an optical plastic material comprising a copolymer prepared by the process. More specifically, the perfluoroalkyl vinyl ether has a particular molecular structure; the process is performed by copolymerizing the perfluoroalkyl vinyl ether compound with a common fluorinated olefin in the presence of a perfluorinated radical initiator; and, the optical plastic material comprises a copolymer prepared by the process and optionally a dopant. The copolymerization of the perfluoroalkyl vinyl ether with a common fluorinated olefin can provide a copolymer having a high molecular weight. In addition, appropriate control of the composition of the monomers can provide a completely amorphous copolymer. Since the polymer prepared by the process exhibits excellent thermal properties and is substantially transparent in the UV and near IR regions, it can be usefully applied to various optical plastic materials. Furthermore, a preform for a GI type plastic optical fiber fabricated by using the copolymer and the dopant has a high Tg, thus being stable, and a parabolic refractive index profile due to the presence of the dopant.
    • 本文公开了新型全氟烷基乙烯基醚化合物,通过使用全氟烷基乙烯基醚化合物制备共聚物的方法,以及包含通过该方法制备的共聚物的光学塑料材料。 更具体地说,全氟烷基乙烯基醚具有特定的分子结构; 该方法通过在全氟化自由基引发剂的存在下使全氟烷基乙烯基醚化合物与普通氟化烯烃共聚来进行; 并且光学塑料材料包括通过该方法制备的共聚物和任选的掺杂剂。 全氟烷基乙烯基醚与普通氟化烯烃的共聚可提供具有高分子量的共聚物。 此外,适当控制单体的组成可以提供完全无定形的共聚物。 由于通过该方法制备的聚合物表现出优异的热性能并且在UV和近IR区域中基本上是透明的,所以它可以有效地应用于各种光学塑料材料。 此外,通过使用共聚物和掺杂剂制造的用于GI型塑料光纤的预成型件具有高T T,因此是稳定的,并且由于存在掺杂剂而具有抛物面折射率分布。
