Abstract
Potassium lithium niobate (KLN: K3Li2Nb5O15) films have been deposited on quartz
glass by Pulsed laser deposition (PLD) technique using a stoichiometric KLN target as starting
materials. By investigating the effects of both the oxygen pressure and the substrate temperature on
the structure of KLN films, optimum parameters have been identified for the growth of high-quality
KLN films. At 10Pa oxygen ambient pressure, tetragonal tungsten-bronze-type structure of KLN
films with (310) preferred orientation can be achieved at substrate temperatures in the range of
700-800°C. Optical studies indicate that the films are highly transparent in the visible-near-infrared
wavelength range.
