How are lasers produced
WebThe use of random lasers for the study of laser action in substances that could not be produced in the form of homogeneous large crystals have also been pointed out as a potential application. Furthermore, in frequency ranges where high-reflectivity mirrors are not available (e.g., gamma-rays, x-rays), the feedback provided by an appropriate scattering … WebLaser wavelength dependence on angular emission dynamics of Nd : YAG laser-produced Sn plasmas J R Freeman, S S Harilal, B Verhoff et al.-Study of the 6. x nm short wavelength radiation spectra of laser-produced erbium plasmas for BEUV lithography Tao WU, , Qian WANG et al.-This content was downloaded from IP address 207.46.13.207 on …
