摘要

得到了20W-50级发动机用机油的非线性光学特性随激光功率的变化规律。这些性质是通过使用z扫描技术在封闭和开放的细胞结构中传输得到的。采用连续波工作的Nd:YAG激光器，发射波长为532 nm，电流可调。为了控制该技术，在LabVIEW中实现了一个接口，可以实时监控测量的发展。估计了非线性吸收系数(b)、非线性折射率(n2)和三阶电导率(x(3))的值，分别为10-3 cm/W、10-9 cm2/W和10-5 esu。上述结果表明，汽车润滑油具有明显的非线性光学特性。

Study of non-linear optical properties in automobile lubricating oil via Z-Scan technique

Non-linear optical properties were obtained as a function of laser power for the 20W-50 multigrade oil for engines. These properties were obtained by using the Z-scan technique for transmission in closed and open cell configurations. A Nd:YAG laser operating in continuous wave (CW) was used, emitting in 532 nm and regulated in electric current. To control the technique, an interface was implemented in LabVIEW, which allows real-time monitoring of the measurement development. The values of the non-linear absorption coefficient (b), non-linear refractive index (n2), and third-order electrical susceptibility (x(3)) were estimated, finding orders of magnitude of 10-3 cm/W, 10-9 cm2/W, and 10-5 esu, respectively. These previous results show that an automobile lubricating oil has significant non-linear optical properties.

期刊介绍： Revista Facultad de Ingenieria started in 1984 and is a publication of the School of Engineering at the University of Antioquia. The main objective of the journal is to promote and stimulate the publishing of national and international scientific research results. The journal publishes original articles, resulting from scientific research, experimental and or simulation studies in engineering sciences, technology, and similar disciplines (Electronics, Telecommunications, Bioengineering, Biotechnology, Electrical, Computer Science, Mechanical, Chemical, Environmental, Materials, Sanitary, Civil and Industrial Engineering). In exceptional cases, the journal will publish insightful articles related to current important subjects, or revision articles representing a significant contribution to the contextualization of the state of the art in a known relevant topic. Case reports will only be published when those cases are related to studies in which the validity of a methodology is being proven for the first time, or when a significant contribution to the knowledge of an unexplored system can be proven. All published articles have undergone a peer review process, carried out by experts recognized for their knowledge and contributions to the relevant field. To adapt the Journal to international standards and to promote the visibility of the published articles; and therefore, to have a greater impact in the global academic community, after November 1st 2013, the journal will accept only manuscripts written in English for reviewing and publication. Revista Facultad de Ingeniería –redin is entirely financed by University of Antioquia Since 2015, every article accepted for publication in the journal is assigned a DOI number.
