The product is a nonlinear crystal designed for efficient wavelength conversion. It has a broad transparency range covering the near and mid-infrared spectral regions, enabling efficient frequency conversion from visible light to the mid-infrared band, including second-harmonic generation (SHG), sum-frequency generation (SFG), and optical parametric oscillation (OPO). Its transparency range can be tailored to output any wavelength within it through periodic structural design, thus meeting the diverse wavelength requirements of modern optics.
