Giant non-linear absorption in Er3+-doped fluoroindate glass
(1999-06-02)
Non-linear absorption is observed in Er3+-doped fluoroindate glass (in mol% 37InF2:20ZnF2:20SrF2:16BaF2:2GdF2: 2NaF:1GaF3:2ErF3) when the sample is irradiated with a CW laser emitting at 650 nm. An intensity dependence of ...

Upconversion of infrared-to-visible light in Pr3+-Yb3+ codoped fluoroindate glass
(1998-08-01)
Bright fluorescence in the visible range has been observed in Pr3+-Yb3+ doped fluoroindate glass under infrared diode laser irradiation. The mechanism which contributes for the upconversion emission is identified and the ...

Self-absorption influence on the optical spectroscopy of zinc oxide laser produced plasma
(Journal of Physics: Conference Series Volume 274, Issue 1, 2011, Article number012079 17th Reunion Iberoamericana de Optica, RIAO and 10th Encuentro de Optica, Laseres y Aplicaciones, OPTILAS; Lima; Peru; 20 September 2010 through 24 September 2010; Code 84476, 2011)
Optical spectroscopy is used to study the laser ablation process of ZnO targets. It is demonstrated that even if Partial Local Thermal Equilibrium is present, self absorption process leads to a decrease of recorded lines ...
