    Image of the LIDCOL-II setup without peripheral LASERs
  • measurement of ultra low absorption and absorption coefficients in bulk material or coatings
  • controlled energy input via pump-beam in measurement wavelength induces a thermal lens
  • measurement of the deflection of the probe-beam
  • minimal measurable absorption coefficient:
    • < 50W/cm in pump-beam wavelength for example fused silica
    • depends on material and wavelength
 
 
CRD (Cavity-Ring-Down) test site for characterisation of high reflective mirrors
    scheme of a CRD setup
  • loss (L) measurement for plane and concave
