Product Features

As a benchmark of innovation in optoelectronic materials, Fuzhou Jingzhi leverages the industrial strengths of the New Quality Productive Forces Center in Fuzhou High‑Tech Zone and the expertise of a top R&D team to launch a series of high‑performance Yb:YAG crystals. With low thermal load, high quantum efficiency, and strong scenario adaptability as its core competitive advantages, the product overcomes the pain points of traditional laser materials — such as thermal lensing and beam‑quality degradation at high power — by utilizing the quasi‑three‑level structure and the proven stability of the YAG host.

Application Fields

Industrial Manufacturing

Compatible with 1030 nm high‑power lasers, it is used for precision metal cutting/welding and micro‑processing of sapphire and glass. After frequency doubling or tripling, the generated 515 nm and 343 nm wavelengths meet the requirements of semiconductor packaging and microelectronics manufacturing.

Scientific Research

Serves as the core gain medium for high‑repetition‑rate femtosecond lasers and disk lasers, and can also act as the pump source for OPCPA systems (optical parametric chirped pulse amplification), supporting ultrafast laser research.

Medical Field

With precise laser output, it is applied in surgical procedures such as ocular tissue repair and removal of pathological skin lesions in dermatology.

Remote Sensing

Its high power and tunability make it suitable for lidar systems, enabling detection of target distance, velocity, and other parameters.
