Presentation: High Power, Watt-class Diode Lasers – Overview of recent progress
Principal, Atacama Optics & Electronics, Santa Barbara, California Chair, IEEE Photonics Society Industry Engagement Committee
High Power Diode Lasers, generating outputs higher than 1 Watt have made significant progress in recent times, enabling applications in many areas, such as Lidar, Free-Space-Optical (FSO) communications, medical diagnostic, defense, materials processing, laser welding and agriculture. These lasers operate over a wide range of wavelengths, from the visible to the infrared. This presentation will provide an overview of the various laser architectures used to achieve these high powers and their key design parameters from a thermal, optical and electrical standpoint. The presentation will also touch on fabrication processes and current state-of-the-art performance. Fabrication and performance of individual diode lasers as well as laser arrays will be discussed. The presentation will conclude with a discussion of the anticipated future evolution of these devices, driven by new applications and supporting second generation quantum technology.

Prof. Giorgio Senesi
Presentation: Laser-induced Breakdown Spectroscopy: Afast in-situ technique applied to identify and discriminate grains and seeds of different nature and detect plant viruses
Geologist and researcher at the Italian National Council Research (CNR), Institute for Plasma Science and Technology (ISTP), Bari seat, Italy.
Laser-induced breakdown spectroscopy (LIBS) is a straightforward and adaptable technique of atomic emission spectroscopy based on focusing a short-duration, fast-pulsed laser beam onto a sample, thus producing a plasma of its constituent elements, which are then detected by spectral analysis of the light emitted. LIBS analysis can be performed quickly in-situ in a laboratory setting or outdoors in a natural setting. Depending on the intrinsic limit of detection of each element in each material, LIBS can analyze almost all elements in the periodic table both qualitatively and quantitatively. In particular, LIBS is especially sensitive to the light elements H, Li, Be, B, and C, which are difficult or even impossible to be analyzed by most traditional techniques. The broadband LIBS spectrum can be thought of as a diagnostic chemical fingerprint.
My talk will illustrate how LIBS has been recently used in different applications to: (i) distinguish among batches of soybean seeds of different physiological quality based on their nutrient content; (ii) identify and discriminate different varieties of conventional (not-genetically modified, NGM) maize from varieties of transgenic maize (genetically modified, GM); and (iii) early detect plant pathogens in order to prevent the dramatic impact they may have on plants.
The potential of routine LIBS application across a wide range of agro-photonics sectors is enormous, but it is currently only partially realized. This is due to the necessity of analytical instrumentation for the quick chemical analysis in the field and the ability of LIBS to analyze any type of material (gas, liquid, and solid) in real time with little to no preparation.

City of São Pedro - SP
São Pedro is a small town in the center of the state of São Paulo. Traditionally known for its natural beauty, the quality of life is the main characteristic of the tourist resort of São Pedro. Located in the interior of São Paulo, the town of just over 38,000 people rests on the slopes of the Serra do Itaqueri mountain range. From afar, it resembles a Neapolitan crib, with its houses among trees, plantations, pastures, and two ancient towers, topped by a cross, marking the grandfatherly faith the settlers brought in the mid-19th century. In the middle of that century, many Italians left their hometown searching for good quality land with plenty of water. They wanted to set up farms and cultivate sugar cane and coffee on a large scale.
At the same time as offering a diversified hotel network for those seeking rest and tranquility, it is visited by thousands of adventurers who enjoy abseiling, jeep trails, hang-gliding and paragliding, hot air ballooning, off-roading, and waterfall bathing.
In addition to the Free Flight Ramp, the resort is known for one of its most beautiful postcards, the Parque do Cristo Aureliano Esteves, where tourists can enjoy the view from above and, on clear days, see neighboring municipalities such as Piracicaba and Rio Claro.
On Boulevard Dona Hermelinda there is an arts and crafts fair on the best local produce. As for the Producer’s Fair, in the Santa Cruz neighborhood on Saturday morning rural people sell vegetables, cheeses, and handmade sweets – and there’s also viola music.
Also in the urban area, you can go for a walk and practice some physical exercise in the Maria Angélica Manfrinato Park. In addition to the pleasant climate produced by various species of trees, there is a beautiful lake, kiosks, a mineral water fountain, a playground for children, and the store of the São Pedro Artisans Association, Art’s Trama.
In addition to the attractions in the city of São Pedro, there are many tourist attractions in nearby towns such as Águas de São Pedro and Brotas, which represent the countryside of São Paulo State.
