#### About LIA

The Laser Institute of America (LIA) is the professional society for laser applications and safety. Our mission is to foster lasers, laser applications, and laser safety worldwide. Serving the industrial, medical, research and government communities for over 50 years, LIA offers technical information, training and networking opportunities to laser users
from around the globe.

#### About LIA Conferences

The conferences of the Laser Institute of America are the town square of the laser community. A large and diverse group, laser professionals often find themselves disconnected from each other. LIA conferences, however, bring the university researcher, the business executive and the production floor user together under one roof for a unique and
rewarding networking opportunity.

#### Program Tracks
Below is the list of all tracks that were on ICALEO 2024 Conference.

##### Laser Additive Manufacturing
* The Laser Additive Manufacturing (LAM) track is a forum to explore the latest innovations and research in laser-based additive manufacturing (LAM). The Laser Additive Manufacturing track focuses on diverse topics, including laser-based powder bed fusion (PBF-LB), directed energy deposition (DED), and other emerging techniques revolutionizing modern manufacturing processes. From materials science to process optimization, from design innovation to industrial implementation, this track connects researchers, engineers, and industry leaders to exchange insights and share breakthroughs in laser additive manufacturing.

##### Laser Materials Macroprocessing
* The Macroprocessing track comprises some of the most productive laser processing applications. Although these applications have been broadly adopted, researchers and industry are persistently innovating to provide new techniques and novel technologies to advance macro materials processing. The attendees will share and discuss those exciting achievements of their research with peers in these macroscopic specialized sessions.

##### Laser Materials Microprocessing
* The Microprocessing track will consist of papers and talks featuring a wide spectrum of applications and innovative equipment for materials processing in microscales with a strong focus on processes with Short and Ultrashort Pulsed Lasers. The presentations will introduce the latest and greatest advancements in their respective fields, presented by world-leading companies and research organizations. This year we will have talks around the headlines of “Beam shaping”, “Glass”, “Surface processing” and “Drilling” between other topics.

##### Frontiers in Laser Applications
* The Frontier in Laser Applications (FLA) track explores recent, cutting-edge applications of lasers, highlighting innovation at the transition of research and industry. The track has included presentations from a variety of fields: Novel 3-D Printing, Advanced Manufacturing, Laser Manufactured Devices, and Frontiers in Laser Processing. The sessions under the Frontier in Laser Application track promise to bring diverse and unique perspectives from real-world applications across laser manufacturing.

##### Laser in Battery Manufacturing
* Electrification is crucial to address global environmental challenges. The laser plays a key role in most manufacturing steps in battery production with all possible laser applications from ablation, structuring, welding, cutting, and marking. Further improvements in the batteries’ power densities, fast charging properties, and yield in battery production are related to photonics and, thus, lasers. We will hear and discuss the latest developments in research, development, and industrial applications. Join us for this year’s Battery Track.

##### Artifical Intelligence in Laser Processing
* The track ‘Artificial Intelligence in Laser Processing’ at ICALEO 2024 explores the fusion of AI and laser manufacturing. Discover cutting-edge research on optimizing laser processes and enhancing manufacturing efficiency. Explore AI’s diverse applications in parameter optimization, quality prediction, real-time process monitoring, and control. Join us to unlock the potential of AI-driven solutions revolutionizing laser materials processing, delivering unprecedented precision, productivity, and innovation.

Features & Benefits of NEXTorr® pumps in e-beam systems

Ultra-deep micro-axicons in lithium niobate by focused Xe ion beam milling

Our goal in this paper is to demonstrate a process flow for the fabrication of silicon tips using KOH based wet etching and Cryo or Bosch based dry etching approaches.

Fabrication of Silicon Micro Tips for Microbial Cell Lysis Applications

We have developed a new technology for detecting single DNA molecules on-chip. A nanofluidic device was fabricated in a multi-step process to unfold the molecules in 3D inlets and guide them inside the nanochannels. No external field is applied, allowing high throughput and generate enormous data in real-time.

High Throughput DNA Optical Mapping in Real-Time on 3D Nanofluidic Devices

Blood separation and processing is a vital and essential step in numerous medical and clinical tests. We present here a unique deformable nanodevice functionalized by three-dimensional (3D) microbeads for plasma separation and blood cells retrieval.

Deformable Microbeads-stacked Nanodevice for Blood Plasma Separation and Blood Cells Retrieval

Label-free optical observation of transparent nano-objects is challenging. We present PlAsmonic NanO-apeRture lAbel-free iMAging (PANORAMA) to image, size, count and monitor single nanoparticle with a size limit approaching sub-10 nm. Molecular imaging is envisioned with functionalized substrates for single nanoparticle analysis for extracellular vesicles (e.g., exosomes) and pathogens (e.g., viruses).

A new label-free plasmonic imaging technique for quantitative analysis of transparent nanoscale objects approaching molecular size

We develop a broadband and omnidirectional tunable resonators with polarization-free high light absorption by preparing a hexagonally patterned array of free-standing SiO2_Ag core-shell nanoparticles. It is the result of hybrid optical modes consisting of Plasmon modes and whispering gallery modes.

Omnidirectional and band-tunable light absorption in free-standing dielectric-metal core-shell resonator arrays

We present optically resonant bipartite metal nano-cylinder arrays fabricated using electron beam lithography. The arrays utilise two different structure sizes with diameter differences as small as 10 nm. We show that this can be achieved and that the arrays show a resonance response that agrees with electromagnetic simulations.

The Fabrication of Bipartite Plasmonic Arrays for Lasing Applications

We demonstrated a technology to experimentally investigate plasmon enhanced fluorescence at the sub-nanometer scale, where strong fluorescence quenching occurs. We have experimentally identified optimal gap sizes for maximum plasmon enhanced fluorescence with tunable dielectric spacers.

Probing the Mechanisms of Strong Fluorescence Enhancement in Plasmonic Nanogaps with Subnanometer Precision

The fabrication of large area silver nano-gratings has been reported using optical interference lithography. The coupling of these plasmonic resonators with optically active quantum dots indicates significant enhancement in photoluminescence signal. Furthermore, The coupling with WS2 monolayers and MoS2/WS2 hetro-bilayers to enhance photocatalytic hydrogen conversion will also be discussed.

Nanofabricated Plasmonic Resonators on Optically Active Materials for Hydrogen Photocatalysis

We describe a closed-loop method for patterning liquid samples using Dip-Pen Nanolithography. The proposed work addresses a pervasive issue in scanning probe lithography, namely real-time closed-loop control over patterning, and scanning probe lithography of liquids as a candidate for the robust nanoscale manipulation of liquids for advanced high throughput chemistry.
