As precision optical components continue to evolve toward miniaturization, array integration, and system-level consolidation, traditional mechanical cold‑machining processes are confronting new challenges in terms of processing efficiency and thermal‑damage control. Ultrafast laser technologies—represented by infrared picosecond and femtosecond lasers—are emerging as a key approach for the precision machining of brittle optical materials, thanks to their distinctive “cold‑processing” characteristics.

　　The core advantage of ultrafast lasers lies in their extremely short pulse durations—ranging from picoseconds to femtoseconds, or 10⁻¹² to 10⁻¹⁵ seconds. Within such brief interaction times, the laser energy completes the processing before heat can diffuse into the material, confining the heat-affected zone to the micrometer—or even sub‑micrometer—scale and achieving near‑zero thermal damage. This characteristic is particularly critical for processing infrared optical materials such as zinc selenide, zinc sulfide, germanium, and silicon, as well as ultra‑thin optical glasses, effectively suppressing microcrack formation and significantly enhancing surface figure accuracy and finish quality.

　　Meanwhile, the industry’s requirements for optical component form are evolving from traditional single lenses toward lens arrays, microlens arrays, and integrated optical modules. This trend calls for cold‑processing stages to possess multi‑process synergy—integrating ultrafast laser cutting, precision grinding, ion‑beam shaping, and other techniques to transition from “single‑step operations” to end‑to‑end process solutions.

　　Industry roadmaps indicate that ultrafast laser “cold‑processing” technology will evolve toward higher average power, larger scan areas, and more advanced intelligent control. As domestically produced ultrafast lasers continue to achieve breakthroughs in performance and cost reductions, the penetration of this technology in optical cold‑processing is expected to accelerate, driving the industry’s profound transition from “conventional manufacturing” to “extreme manufacturing.”

　　In response to the aforementioned changes in the industry landscape, our company will continue to focus on innovating ultra-precision optical cold‑processing technologies, enhance our capabilities in manufacturing core products such as infrared optical components, and provide downstream optoelectronic enterprises with higher‑quality ultra‑precision manufacturing solutions.
