Asahi Kasei Microdevices achieves 2-micrometer band infrared laser oscillation through light source optimization
Tuesday, March 17, 2026 at 02:40 AM
Asahi Kasei Microdevices (AKM) and Nagoya University have successfully achieved 2-micrometer band infrared laser oscillation by optimizing the light source structure. This technical advancement in semiconductor laser technology focuses on high-efficiency light emission for industrial and sensing applications.
Context
Asahi Kasei Microdevices (AKM) has successfully achieved infrared laser oscillation in the 2-micrometer (2μm) band through the optimization of light source structures. This development is significant as the 2μm wavelength falls within the "eye-safe" region, where light is strongly absorbed by water and biological tissue. This characteristic makes these lasers ideal for high-precision medical surgery, where they can cut tissue with minimal penetration depth and suppressed bleeding via coagulation. As of March 2026, this breakthrough positions AKM to capture expanding demand in the medical, environmental, and industrial sectors.
Beyond healthcare, 2μm lasers are critical for the next generation of LIDAR and gas sensing technologies. They enable the detection of atmospheric gases such as CO2 and N2O, supporting carbon neutrality monitoring and weather forecasting. By refining the light source structure, Asahi Kasei improves the efficiency and feasibility of semiconductor lasers in this band, which traditionally required more complex fiber laser setups. This advancement strengthens the company's position in the high-growth sensor and optical component supply chain for autonomous systems and environmental monitoring.
