Reflectivity of picosecond neodymium laser pulses in germanium Academic Article uri icon


  • The reflectivity of picosecond pulses from a Nd: glass laser on Ge has been measured. A marked increase ({reversed tilde} 20%) has been found at excitation intensities just below the damage threshold. The effect is discussed in terms of the contribution to the dielectric constant of the crystal, arising from direct intraband transitions within the branches of the valence band. The relevance of these transitions to explain the "plateau" observed in the transmission experiment, is also briefly pointed out. 1978.
