Introduction
CASTECH designs and fabricates high reflectivity mirrors with high laser damage threshold for most demanding laser applications. We utilize super polishing and ion beam figure (IBF) technologies to prepare high-quality substrates. With multiple advanced coating systems and technologies, coupled with high accuracy total loss measurement based on Cavity-Ring-Down (CRD) and LDT measurement, we are able to deliver consistent high-quality mirrors featured not only high reflectivity, but high laser damage resistance and environmental stability.
Metrology
CASTECH has the ability to accurately measure ultra-high reflectivity using the cavity ring down method (CRD). It can measure the ultra-high reflectivity of ultra-high reflectivity components in the 532 nm, 1064 nm, and 1550 nm bands, with a testing range of 99.9% to 99.9995%. CRD technology is a cavity mirror oscillation testing technique that measures the duration of laser oscillation in the laser cavity, thereby measuring the reflectivity of the component. It is a high-precision measurement method for ultra-high reflectivity.
