Optical beating methods
WebJun 1, 2001 · An overview of existing methods of wavelength and wavelength instability measurement is presented. The methods are classified on the basis of the applied physical phenomena. Three main groups are distinguished: interference comparators, optical beating methods, and methods using specific wavelength-dependent material properties. Webmaking this method technically challenging. In this paper, we propose a simple technique to enhance the peak power of the attosecond radiation pulse while maintain the ultrashort duration. In the proposed scheme, the optical beating technique is utilized to compress the electron beam [34]. Different from other methods, two infrared lasers with
