Laser ablation deposition of Ga2S3-La2S3 glass films

Asal, R., Rivers, P.E. and Rutt, H.N. (1995) Laser ablation deposition of Ga2S3-La2S3 glass films At Materials Research Society Symposium, United States.

Record type: Conference or Workshop Item (Paper)


Gallium - lanthanum sulphide glasses (GLS) show wide range transparency and low non radiative relaxation rates for dopant ions such as Ho3+, Er3+ etc. They also show permanent photomodification of the refractive index under visible illumination. We report laser ablation deposition of these glasses and preliminary results on film stoichiometry and deposition rate as a function of excimer laser fluence. The sulphur to metal and Ga/La ratios are found to have marked fluence dependencies. The films show considerably more Urbach tail absorption than bulk material. A novel method has been developed for mapping the permanent photomodifled index.
