Comparative reflectance measurements on laser-produced plasmas at 1. 06 and 0. 53. mu. m
Journal Article

· Phys. Rev. Lett.; (United States)
The total and specular reflectances of 1.06- and 0.53-..mu..m laser pulses were measured on planar copper targets. The measurements were made with 30-ps pulses and an intensity on target of 10/sup 14/ W/cm/sup 2/. The direction of polarization and angle of incidence (0 /sup 0/--70 /sup 0/) were varied. Only a weak dependence of reflectance on wavelength is found; at both wavelengths reflectance is governed by the characteristic angle and polarization dependence of resonance absorption.
