We present an overview of laser results we obtained with Yb-doped calcium fluoride and its
isotype strontium fluoride. In order to study the laser performance in femtosecond and high …

Here is presented and discussed the history, the spectroscopic, the thermo-mechanical and
the laser properties of the new old laser crystal Yb: CaF 2, of its Sr and Ba isotypes as well …

Fluoride compounds have compelling advantages for many optical applications due to their
unique combination of low phonon energy, high UV absorption edge energy, and relatively …

A detailed spectroscopic study of Yb 3+: CaF 2 is made by using laser selective excitation,
low-temperature time-resolved fluorescence, and Raman techniques. Three dominant types …

The origin of light scattering defects was studied in transparent 6 at% Yb: CaF 2 ceramics.
Samples were synthesized by a soft chemistry route followed by sintering and hot pressing …

In Yb: CaF2, the coordination of Yb3+ in the CaF2 lattice determines the spectroscopic
properties that make Yb: CaF2 a good candidate for high power laser applications. In this …

We report an in situ thermal study of Yb-doped fluorite crystals Yb: CaF_2 and Yb: SrF_2
under high power pumping, with or without laser operation. The experiment combines …

Various ternary aluminosilicate glasses with the molar compositions 20 Al2O3–60 SiO2–20
R2O (R= Li or Na), 20 Al2O3–60 SiO2–20 RO (R= Mg, Ca or Zn) and 23.1 Al2O3–69.2 SiO2 …

We demonstrate the generation of 99 fs pulses by a mode-locked laser oscillator built
around a Yb: CaF_2 crystal. An average power of 380 mW for a 13 nm bandwidth spectrum …

Using a novel (to our knowledge) broadband Yb-doped Yb^ 3+, Na^+: CaF_2 crystal cooled
in a closed loop to 130 K we demonstrate a chirped pulse regenerative laser amplifier …
