Chengdu Yagcrystal Technology Co., Ltd.is an innovative enterprise that integrates precision,novelty,and high-tech.We have been deeply involved in the field of laser technology for nearly 20 years,providing one-stop services from crystal research and development to precision machining and coating.
The concentration gradient crystal independently developed by the company has greatly promoted the development of end pump laser technology,and has been mass-produced on multiple models in the fields of end pump laser ranging and laser irradiation; Simultaneously involved in research and development in fields such as laser countermeasures,laser imaging.
Our company's precision optics business involves various materials such as sapphire and diamond,K9,Quartz,silicon,germanium, CaF2,ZnS,ZnSe,YAG,etc;We perform high-precision machining,coating,and metallization on flat,spherical,and non spherical surfaces. The typical characteristics are: large size,high precision,ultra smooth,and high damage resistance threshold.Taking sapphire as an example,our smoothness can achieve 10/5 and PV ≤ 1/20, RMS≤1/50，Ra≤0.1nm。 Damage threshold ≥ 70J/cm2.
Our products are widely used in various equipment such as satellites,helicopters,drones,ships,armor,vehicles,etc.,and have won the trust and recognition of customers with stable performance and high reliability quality.
