Abstract

The invention relates to a high-light-transmittance deep-freezing laser impact head and laser impact system suitable for deep freezing laser impact technology. The temperature-insulation ceramic/plastic and vacuum temperature-insulation method are utilized to prevent water in air from being adsorbed onto high-transmittance glass due to low temperature and solve the problem that liquid nitrogen vapor can not be light-transmitting, thereby ensuring the light beam quality in the deep-freezing laser impact process. The high-light-transmittance deep-freezing laser impact head is characterized by comprising an upper end cover, a main body, a lower end cover, high-transmittance glass, a heat-insulation ceramic/plastic and other core components. The high-light-transmittance deep-freezing laser impact head ensures the light beam to smoothly reach the sample surface in the deep-freezing laser impact process, effectively enhances the light transmittance of the laser, has the advantage of simple structure, and is easy to implement.

Description

technical field [0001] The invention relates to the field of laser shock and cryogenic processing, in particular to a cryogenic laser shock technology, which improves the light transmittance of the laser through heat-insulating ceramics / plastics and vacuum insulation methods, thereby ensuring the cryogenic laser shock process The beam quality in it, specifically a cryogenic laser shock head with high light transmittance and its system. Background technique [0002] Cryogenic laser shock technology utilizes the coupling effect of ultra-low temperature and high strain rate, which can significantly improve the microstructure and residual stress state of the material, greatly improve the fatigue resistance and wear resistance and corrosion resistance of the material, and is expected to be used in many fields such as aviation, automobiles, and ships. widely used. However, the cryogenic laser shock temperature is as low as -196°C. The low temperature resistance of the laser shock...
