   Abstract : Lithium niobate (LiNbO3) and KTiOPO4 (KTP) are ferroelectric crystals of considerable interest in different fields of optics and optoelectronics. Due to its large values of the nonlinear optical, electro-optic (EO), piezoelectric and acousto-optical coefficients, LiNbO3 is widely used for laser frequency conversion using the quasiphase matching (QPM) approach where the sign of nonlinearity has been periodically modulated by electric field poling (EFP).

4. 2. Nanofabrication of Zone Plates for Hard X-Ray Free-Electron Lasers

   Author : Fredrik Uhlén; Ulrich Vogt; Thomas Wilhein; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; X-ray optics; Zone plates; Nanofabrication; X-ray free-electron lasers; Fysik; Physics;

   Abstract : This Thesis describes the development of hard X-ray zone plates intended for focusing radiation at X-ray free-electron lasers (XFELs). XFELs provide unprecedented brightness and zone plates which are put in the intense X-ray beam are at risk of being damaged. READ MORE
