Abstract :
Zn:Fe:LiNbO3 crystals with different Li/Nb
ratios in the melts (Li/Nb = 0.946, 0.97, 1.00, 1.10, 1.20,
1.44) have been grown for the first time. The UV–Vis
absorption spectra, exponential gain coefficient, diffraction
efficiency and response time of the crystals
were measured. With the ratio of Li/Nb increasing, the
absorption edge shifts to a shorter wavelength, the
exponential gain coefficient and response speed increase,
but the diffraction efficiency decreases.
