Photo-expansion of the bulk of (GeS2)(0.74)(Sb2S3)(0.26) glass induced by sub-gap photons is studied employing specifically atomic force microscopy (AFM) namely an atomic force acoustic microscopy (AFAM) and a force spectroscopy and digital holographic microscopy. The results are discussed with respect to the possible role of light induced overheating in the process of photo-expansion. (C) 2012 Elsevier Ltd. All rights reserved.
