    • Anisotropy of the photo-elastic effect in Nd : KGd(WO4) 2 laser crystals 

      Loiko, P. A.; Savitski, V. G.; Kemp, A.; Pavlyuk, A. A.; Kuleshov, N. V.; Yumashev, K. V. (Wiley, 2014)
      The anisotropy of thermal lensing and the photo-elastic effect is characterized for diodepumped Nd : KGd(WO4)2 crystals cut along the Np and Ng optical indicatrix axes and along its optical axis, O = Ng + 43°, at a laser wavelength of 1067 nm. Distortions in the spatial profile of the output laser beam are analyzed. The thermal lens is astigmatic; the orientation of its principal ...

    • Simplified method of calorimetric measurements of background loss in crystals 

      Savitski, V. G.; Kemp, A. (БНТУ, 2012)
      We report on the measurements of absorption coefficient of the synthetic diamond crystal using an adapted form of laser calorimetry technique at wavelengths of 1064, 640, 532, 452 and 364 nm. The absorption coefficient was found to increase exponentially from 0,03 cm-1 at 1064 nm to 0,7 cm-1 at 364 nm.
