TL;DR: Several different compositions of tellurium-thallium glasses were fabricated and tested for their Raman gain performance and the maximum Raman Gain experimentally obtained was higher than the peak Raman loss of fused silica.
Resolved discrepancies between visible spontaneous Raman cross-section and direct near-infrared Raman gain measurements in TeO2-based glasses.

TL;DR: A multi-wavelength Raman cross-section experiment was conducted on two different TeO2-based glass samples, and the estimated Raman gain response of the material shows good agreement with the directly-measured Raman Gain data at 1064 nm.
Raman gain measurements and photo-induced transmission effects of germanium- and arsenic-based chalcogenide glasses.

TL;DR: The Raman gain spectra of millimeter thick As(2)S(3) and As(24)S (38)Se(38) glasses and Ge((23 - x))Ga(x)Sb(7)S((70 - y))Se(y) with x and 5 and y = 0, 2, 5 have been measured using a direct nonlinear optics technique.

Raman gain measurements in bulk glass samples
Robert Stegeman,Clara Rivero,George I. Stegeman,Peter J. Delfyett,Kathleen Richardson,Ladislav Jankovic,Hong-Ki Kim +6 more
TL;DR: In this article, the authors present an experimental apparatus to measure the material Raman gain coefficient on millimeter-thick bulk glass samples. But they do not discuss the performance of the apparatus.

Clara Rivero,Robert Stegeman,Kathleen Richardson,George I. Stegeman,G. Turri,M. Bass,Philippe Thomas,M. Udovic,Thierry Cardinal,Evelyne Fargin,Michel Couzi,Himanshu Jain,A. C. Miller +12 more
TL;DR: In this paper, five different glass compositions with equal TeO2 molar concentration and various intermediate constituents were examined to examine the influence of such intermediate species on the tellurite network.
