Phys. Rev. Lett. 42, 1625–1628 (1979)Comparative Reflectance Measurements on Laser-Produced Plasmas at 1.06 and 0.53 μmReceived 28 March 1979; published in the issue dated 11 June 1979 The total and specular reflectances of 1.06- and 0.53-μm laser pulses were measured on planar copper targets. The measurements were made with 30-ps pulses and an intensity on target of 1014 W/cm2. The direction of polarization and angle of incidence (0°-70°) 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. © 1979 The American Physical Society URL:
