Second harmonic generation in lead-containing glasses based on alkaline-earth metaphosphates
Autor: O. S. Shchavelev, A. I. Valeev, V. M. Churikov, K. O. Shchavelev
Publikováno v: Glass Physics and Chemistry. 26:409-413
An efficient second harmonic generation in the quadratic polarizability gratings (χ(2)-gratings) written in lead-containing glasses based on barium, strontium, and calcium metaphosphates has been observed. It is shown that the generation efficiency

Athermal optical glasses and thermally stable space-based apochromats (from the materials of a report at the International Conference ??Applied Optics?2002')
Autor: O. S. Shchavelev, L. N. Arkhipova
Publikováno v: Journal of Optical Technology. 70:576
A basis is provided for choosing thermooptical parameters V and W1R as the true criteria of athermal glasses that minimize temperature distortions in space-based objectives. Previously unpublished results are presented from our studies, involving the

High-gain phosphate neodymium glass rod amplifiers with 60 mm diameter
Autor: Vladimir E. Yashin, Aleksandr V Charukhchev, O S Shchavelev, E G Bordachev, V I Kryzhanovskiĭ, V A Serebryakov, V I Bayanov
Publikováno v: Soviet Journal of Quantum Electronics. 14:213-216
An experimental investigation was made of the parameters of 60-mm-diameter amplifiers pumped in various enclosures. A study was made of the influence of flashlamps, nature of the enclosure, and neodymium concentration on the gain. The maximum output
