Polished Undoped 4h Semi Sic Single Crystal Rod Lens high purity

SiC crystal is an important wide-band gap semiconductor material. Because of its high thermal conductivity, high electron drift rate, high breakdown field strength and stable physical and chemical properties, it is widely used in high temperature, In high frequency and high power electronic devices. There are more than 200 types of SiC crystals that have been discovered so far. Among them, 4H- and 6H-SiC crystals have been commercially supplied. They all belong to the 6 mm point group and have a second-order nonlinear optical effect. Semi-insulating SiC crystals are visible and medium. The infrared band has a higher transmittance. Therefore, optoelectronic devices based on SiC crystals are very suitable for applications in extreme environments such as high temperature and high pressure. Semi-insulating 4H-SiC crystal has been proved to be a new type of mid-infrared nonlinear optical crystal.

Compared with commonly used mid-infrared nonlinear optical crystals, SiC crystal has a wide band gap (3.2eV) due to the crystal. , High thermal conductivity (490W/m·K) and large bond energy (5eV) between Si-C, so that SiC crystal has a high laser damage threshold. Therefore, semi-insulating 4H-SiC crystal as a nonlinear frequency conversion crystal has obvious advantages in outputting high-power mid-infrared laser. Thus, in the field of high-power lasers, SiC crystal is a nonlinear optical crystal with broad application prospects. However, the current research based on the nonlinear properties of SiC crystals and related applications is not yet complete. This work takes the nonlinear optical properties of 4H- and 6H-SiC crystals as the main research content, and aims to solve some basic problems of SiC crystals in terms of nonlinear optical properties, so as to promote the application of SiC crystals in the field of nonlinear optics.
