The highly anticipated IEEE Photonics Conference (IPC) 2025 will take place in Singapore, November 9–13, 2025. As one of the most prestigious and influential events in the global photonics community, IPC brings together leading experts, researchers, and industry leaders from around the world to discuss the latest advancements and emerging trends in photonic technologies.

Dr. Xingsheng Liu, CEO of Focuslight Technologies Inc., has been invited to deliver an invited talk at the conference. His presentation, titled “Scaling of Pumping Sources for High-Power Diode-Pumped Solid-State Lasers: From Technology to Mass Production”, will highlight Focuslight’s technological breakthroughs that are driving scalable and cost-effective manufacturing for high-power DPSSL applications.

In his talk, Dr. Liu will share Focuslight’s key innovations in photonics manufacturing and discuss how the company leverages advanced automation and batch production technologies to continuously enhance scalability and cost competitiveness in the production of diode laser pumping sources for high-power solid-state lasers.

The presentation will focus on several major innovations and achievements, including:

• Wafer-level micro-optics fabrication technology – enabling high-precision, high-consistency, and high-yield volume production;
• “sheet”-level bar bonding substrates production – supporting efficient and uniform large-scale processing;
• Innovative batch process bar bonding – significantly increasing production capacity and cost efficiency;
• Automated optical assembly, testing, and inspection systems – ensuring product reliability, stability, and consistency in high-volume manufacturing.

With these advancements, Focuslight has successfully achieved efficient, scalable mass production of high-power DPSSL pumping sources, while continuously delivering high-quality, cost-effective components and solutions for industrial, medical, and scientific applications.

Focuslight’s product portfolio includes preform AuSn pre-deposited substrates, diode laser components, laser optics, and side-pumped solid-state laser modules. These products have been widely adopted by leading laser manufacturers worldwide, earning strong recognition for their reliability and performance.
