The need of new materials with desirable optical properties has become important in recent
years. In particular, a need has emerged for compounds having better luminescence …

High‐power all‐fiber thulium lasers have gained considerable interest in recent times due to
their distinct characteristics and versatile applications in the medical and industrial sectors …

Nonlinear optical techniques are now recognized as the most efficient means available to
generate laser radiation at wavelengths that are presently inaccessible via conventional …

The spectroscopic and laser kinetic properties of the trivalent ytterbium ion in various solid-
state media are reviewed. Contrasts between four-and quasi-three-level lasers (eg, Nd: YAG …

Cuprorivaite (CaCuSi4O10, also known as Egyptian blue) exhibits an exceptionally high
emission quantum efficiency in the near-infrared region (λmax= 910 nm, ΦEM= 10.5%) and …

Crystal-field effects are very important as far as laser performances of Yb-doped materials
are concerned. In order to simplify the interpretation of low-temperature spectra, two tools …

We report 1.1 W CW green output from a diode-end-pumped self-frequency-doubled (SFD)
Yb: YAB laser, with a diode-to-green optical conversion efficiency of 10%. This is five times …

Well-characterized solid-state laser materials are evaluated for performance in optical
refrigeration as well as radiation-balanced laser systems. New figures-of-merit are …

Using a model for the quasi-three level laser dealing with gaussian waves, taking into
account the saturation of the pump, the stimulated emission at the pump wavelength, the …

The main properties of the Nd 3+→ Yb 3+(4 F 3/2, 2 F 7/2→ 4 I 9/2, 2 F 5/2) energy transfer
in yttrium aluminum borate nonlinear laser crystal have been studied. This host has been …
