We demonstrate a 968-nm LD side-pumped Er:YAP laser with concave end-faces and a
working frequency of 50∼1000 Hz. The maximum average powers of 26.75 and 13.18 W
are obtained at 250 and 1000 Hz, corresponding to the slope efficiency of 16.2%
and 9.0%, respectively. The M2 factors of 7.98 and 1.49 are determined under the
multi-mode and single-mode, and three laser wavelengths of 2713, 2732 and

Improved omnidirectional reflectors in chalcogenide glass and polymer by using the silver doping techniqueOptics Express - Tập 14 Số 5 - Trang 1789-1796 - 2006

We describe the fabrication and characterization of omnidirectional reflectors
based on silver-doped chalcogenide glass and polymer. We deposited periodically
alternating layers of thermally evaporated Ge33As12Se55 chalcogenide glass,
sputtered silver, and spun-cast polyamide-imide polymer. The silver was
subsequently dissolved into each adjacent chalcogenide glass layer, either by
exposing the mu... hiện toàn bộ
