Stimulated Raman scattering in water and liquid nitrogen is studied near the liquid-air interface at picosecond (15 and 57 ps) laser excitation. For the first time, it is shown that Raman threshold on the interface is crucially reduced (up to 30-fold

Avalanche-like up-conversion at nonlinear coupling of pumping channels: effect of ions concentration
Publikováno v:
2020 International Conference Laser Optics (ICLO).
We report results on avalanche-like effect in up-conversion on Er ions-doped in KGW crystal for concentrations of 1 and 10−4 wt.%. Our experimental and theoretical data point to the conclusion, that avalanche-like behavior observed earlier at low t

We report an experimental observation of the upconversion in fluorophosphate glasses doped with different concentrations of Tm3+ ions (from 1020 to 1015 ion/cm3) and a constant content of Yb3+ ions (1021 ion/cm3) when pumped by a diode laser with a w
