What is ICALEO?
The International Congress on Applications of Lasers & Electro-Optics (ICALEO) is where the global laser community gathers to exchange research, compare approaches, and explore new directions in laser applications, materials processing, and electro-optics.
For more than four decades, ICALEO has provided a setting where technical depth and open collaboration go hand in hand. Researchers, engineers, business leaders, and students come together to share insights that advance both their work and the broader field.
Participants value ICALEO not only for its rigorous technical program, but also for its approachable, community-driven environment. Whether you’re presenting new findings, evaluating emerging capabilities, or looking for partners on a complex challenge, ICALEO offers a space designed for meaningful exchange among people who are deeply invested in laser innovation.
Who should attend?
ICALEO brings together a diverse international audience working across the full landscape of laser research, development, and application. Attendees typically include:
- Post-graduate students presenting early research and building professional connections.
- Professors and laboratory directors sharing new results and forming collaborations with industry and government partners.
- Scientists from national and government laboratories contributing applied research and learning from global counterparts.
- Laser applications engineers exploring processing techniques, system capabilities, and implementation challenges.
- Bio-effects and biomedical laser researchers investigating laser–tissue interaction, photo-biomodulation, and emerging bio-photonic applications.
- Medical and life-science technology developers advancing clinical, diagnostic, and biologically oriented laser systems.
- Industry strategists and technology leaders examining long-term trends and identifying new opportunities.
- Laser and optics sales and business development professionals engaging with engineers, researchers, and technical buyers.
This blend of perspectives ensures that technical conversations span multiple disciplines—from advanced manufacturing to biophotonics—creating opportunities for insights and collaboration across sectors.

Ways to Participate
There are several ways to take part in ICALEO:
- Attend the conference. Join researchers, engineers, and industry leaders for technical sessions, discussions, and networking events.
- Submit your work. Contribute an oral presentation or poster and play a role in shaping the technical program.
- Exhibit or sponsor. Connect with a global audience of engineers, scientists, program leaders, and decision-makers who influence technical direction and purchasing strategies.
Engaging with ICALEO places you in a community that has been advancing lasers, laser applications, and laser safety for nearly five decades, and continues to move the field forward through collaboration, research, and shared expertise.
Why It Matters
Work in lasers, materials processing, and photonics advances quickly. Staying current requires more than reading publications or scanning trade show floors. For over 40 years, ICALEO has offered a unique combination of:
- Technical depth — peer-reviewed content presented by the people doing the work.
- Cross-sector insight — perspectives from academia, industry, and government that highlight both challenges and opportunities.
- Practical relevance — discussions that connect experimental findings with real applications in manufacturing, aerospace, energy, medical environments, and more.
- Community — a professional environment where attendees ask thoughtful questions, exchange candid insights, and support one another’s progress.
Students and early-career professionals gain an encouraging place to learn and present. Experienced attendees rely on ICALEO as a trusted forum for technical dialogue and strategic exploration. Sponsors and exhibitors benefit from direct engagement with an audience that understands the nuances of the work and values expertise.
