Abstract :
Monoclinic Eu:KY(WO4)2 laser crystals are grown by TSSG method; polarization-resolved absorption and stimulated-emission cross-section spectra are determined for this crystal. Spectroscopic properties are modeled within ASCI theory. Under UV excitation, Eu:KY(WO4)2 provides intense red emission with CIE coordinates x = 0.670, y = 0.329.
