Due to the short startup time, high-speed processing is possible!

The resonator structure of CERAMICORE, patented by the U.S. company IRADION, differs from conventional resonator structures in that the metal electrodes do not come into contact with the laser gas, preventing degradation of the laser gas. This results in a long lifespan, high output stability, high pointing stability, high beam quality, and excellent pulse characteristics of the laser beam. The Infinity Plus series offers even greater stability than the Infinity series, with a shorter pulse rise time (less than 40 μs), making it suitable for stable high-speed processing such as drilling. The output types range widely from 50 to 100W, and the oscillation wavelengths can be selected from 10.6 / 10.2 / 9.3 µm. The compact design of IRADION's CO2 lasers makes it easy to replace existing CO2 lasers currently in use. There are also options available for dedicated controllers, beam expanders, high-speed pulse detectors, and more.

It is possible to measure CO2 laser light pulses at high speed.

The high-speed detector (power meter) for CO2 lasers from Germany's Fortec HTS company employs a thermoelectric element with a fast response speed (rise time of 1μs @300kHz) to measure the pulses of CO2 laser light. While it cannot measure laser output in absolute values, it is used to detect output fluctuations in relative values. There is also a type with a rise time of approximately 400ns available. Please prepare the DC power supply (±15V) and cooling equipment yourself.

[Speaker] Tomio Shida, Special Analyst, Japan Metal Economic Research Institute, General Incorporated Association [Key Lecture Content] The importance of metals is increasing, from rare metals such as rare earth elements to copper. While the demand is expanding due to the construction boom of data centers supporting the spread of AI (artificial intelligence), renewable energy, and the proliferation of EVs, supply concerns are rising due to resource nationalism and environmental issues. Geopolitical risks, including the turmoil in the Middle East, and global divisions are making stable procurement difficult. China, which has increased its presence in the field of metal refining, is shaking up the supply chains of Japan, the U.S., and Europe not only with export regulations but also with low-price exports. The U.S. added ten types of metals, including copper, to its revised critical minerals list last year. How should Japanese companies respond? [Lecture Topics] 1. "Critical Minerals" Changing with the Times 2. Future Technologies, including AI and EVs, Depend on Metals 3. Increasing Challenges and Costs in Mining Development 4. How Do Changes in International Situations, Such as Tensions in the Middle East, Affect Us? 5. China's Disruptions Go Beyond Export Regulations - Challenges in Building Supply Chains 6. Are Japanese Companies Prepared to Accept "Increased Costs"? 7. Q&A / Business Card Exchange

[Lecture Topics] 1. The Current State of Japan's Automotive and Battery Industry and the Challenges of Why We Should Pay Attention to China's Latest Trends (AI and SDV) Shinya Okimoto, Founder & CEO of Okita Studio LLC 2. Report on the Beijing Motor Show and Explanation of China's Latest Automotive and Technology Trends Jeong-kyu Park, Concurrent Professor at KAIST Graduate School of Technology Management 3. Panel Discussion Shinya Okimoto, Founder & CEO of Okita Studio LLC Jeong-kyu Park, Concurrent Professor at KAIST Graduate School of Technology Management

[Speaker] Masaharu Takano, President and CEO of Bit Media Inc. President and CEO of MESH-X Inc. [Key Lecture Content] With the spread of generative AI, the power demand for data centers (DC) has surged, and the integration of power (watts) and communication (bits) known as "Watt-Bit Collaboration" is emerging as a national strategy. In this lecture, we will outline the latest trends in domestic policy and explain key technologies such as "workload shift," which maximizes the use of available capacity in the power grid, "virtual hyperscaler," which virtually consolidates distributed locations, new trends in next-generation waste heat technology for DCs, and next-generation communication infrastructure like IOWN/APN. Additionally, we will incorporate international examples, such as the AI data center power flexibility demonstration in Phoenix, USA, to illustrate how companies should prepare for the sharp rise in electricity costs in the AI era and indicate the direction for implementing digital infrastructure.

Event Name: Messe Nagoya 2026 Date: November 11, 2026 - November 13, 2026 Location: Port Messe Nagoya This is our first time exhibiting at a large event. We will do our best, so please stop by our booth when you visit.

An explanation of the "detailed risk assessment of hazardous areas," which is essential as the first step in promoting smart security and digital transformation in hazardous material facilities.
