Orthogonally linear polarized lasers(Ⅰ)--principle and devices

Two kinds of orthogonally polarized lasers, i.e. Zeeman dual-frequency lasers and four-frequency ring lasers (laser gyros) have been developed since the invention of lasers, in which circularly polarized lights oscillate. This paper summarizes recent progress of the study on orthogonally linear polarized lasers with the standing wave cavity. Firstly, the expression of producing orthogonally linear polarized lights in standing wave cavity, i.e. laser frequency splitting, is given. Almost all the birefringence effects made in laser cavity are used to produce orthogonally linear polarized lights. The effect includes quartz crystal birefringence effect, calcite birefringence effect,stress (photo-elastic) birefringence effect and electro-optical birefringence effect. Secondly, several physical phenomena of orthogonally linear polarized lasers are discovered such as aberrance of frequency splitting curves caused by optical activity of quartz crystal, order-passing of longitudinal modes with frequency splitting and strong modes competition. Finally, because the traditional Zeeman dual frequency laser cannot output frequency difference larger than 3 MHz, the approaches of obtaining larger frequency difference are studied. The sequential results, several kinds of orthogonally polarized lasers, are described, such as birefringence dual frequency lasers outputting a frequency difference from 40 MHz to hundreds of megahertz, birefringence-Zeeman dual frequency lasers outputting a frequency difference from 1 MHz to hundreds of megahertz, the LD pumped YAG birefringence dual frequency laser outputting frequency difference of several gigahertz, and the lasers whose longitudinal mode spacing is c/4L instead of c/2L.     

论技术主体的社会建构

技术主体是与作为客体的技术相互对立,相互依存,并以对方的存在为存在基础的一对哲学范畴.技术主体是在技术产生、发展、应用和完善过程中起主导性作用的角色.技术作为人的主体性的展现,作为一种社会现象和社会行动,通过与人和社会的互动,社会地建构了技术,同时人也在根据由自身推动的技术发展的进程和模式塑造和建构着人类自身,并被多种社会因子所建构.这种建构从本质上表现为历史性、社会性与过程性的统一.

反思的现代性与技术理性的解构--海德格尔和福柯论现代技术问题

海德格尔和福柯对于现代技术问题的思考属于某种反思的现代性立场：无论前者对机械技术的本质的追问，还是后者对自我技术的谱系学分析，都没有简单地否定现代技术，而是揭示了现代技术的解蔽和遮蔽双重性。这样的立场告诉我们：面对现代技术的极度张扬，哲学应该坚持一种保守主义姿态，应该在更新的意义上恢复经验的地位。
