Abstract
To satisfy the application requirements of sapphire output window for the 170 GHz megawatt-class gyrotron short-pulsed experiment,by calculating the characteristic of reflection and absorbing of Gaussian beam transmitted through sapphire window,a sapphire window unit is designed with low reflection and low loss power.The low reflectance is verified by vector network analyzer that the Voltage Standing Wave Ratio(VSWR)<1.1.The maximum output average power threshold of the sapphire window has been calculated approximately to be 590 W by analyzing the damage mechanism.The 170 GHz gyrotron employing sapphire window is fabricated,and the power threshold calculated theoretically is verified,providing a reliable theoretical basis for the application of sapphire output window used in high power gyrotron.关键词
