College educators have an implicit obligation to teach students today about optics and photonics for the jobs of tomorrow. This experiment is designed for upper-level undergraduates to work in a femtosecond laser lab. The optics are aligned prior to students arriving in the lab for ease of instruction. While performing the experiment, students are allowed to move a translation stage, which functions to overshoot or delay the arrival of the translation arm laser pulse at a nonlinear beta-barium borate (BBO) crystal relative to the arrival of the stationary arm laser pulse. Ultimately, students generate an autocorrelation of the laser pulse using second harmonic generation (SHG) from the BBO crystal and the femtosecond pulse duration. Students benefit from seeing the inner-workings of a femtosecond laser and the experimental setup. Moreover, they begin to understand SHG, consider laser applications, and get a glimpse of a possible career focus.

Abstract.The Relationship Networks Project (RR -Redes de Relacionamento)is an innovative project, which intends to create a framework, which allowsthrough a fast data modeling -implementing interface elements that describe in a clearly visual way, in two-dimensional presentation, a relationship network among heterogeneous items. This environment also allows the machine to do operations over these relations, such as to find paths or sets, to help the implementation of AI algorithms, or data extraction by the final user. Through graph theory, with visual items, it is possible to find elements with specific characteristics and relationships between them, by the application of filters, refining searches inside an extreme large datasets, or showing differentiated connection maps. Two prototypes were created with this framework: A system which allows seeing telephonic calls sets and financial transactions, and a system for ontology viewing for a digital dictionary inside a semantic network. Another software, in prototypical phase, also for semantic network vision, is being constructed. This document will present the basic RR structure, showing and justifying the creation of the two referred software above.
