In the work, the first principles calculation and low temperature spectra were utilized to
investigate the modification on Nd 3+ clusters in SrF 2 crystal. The results show that …

Based on a novel disordered fluoride crystal—Nd 3+ and Gd 3+ co-doped CaF 2, we
demonstrate a dual-wavelength synchronously mode locked laser in a single cavity, for the …

The neodymium cluster evolution in fluorite crystals has been unknown for nearly 60 years,
which hindered further exploration of rare-earth-doped fluorite materials. In this work, the first …

Langasite crystals with an ordered structure of space group P321 are well known for their
excellent piezoelectric and nonlinear optics performance. In this paper, a novel Nd 3+: Ca 3 …

Trivalent rare earth ions have rich and unique energy levels arising from 4f inner shell
configurations, which can be widely used in lasers, display, and bioimaging, etc. As the ff …

Abstract 0.5–5%(atom percent) Nd 3+-doped SrF 2 transparent ceramics were fabricated by
hot-pressed sintering and the effects of Nd 3+ doping content on microstructure and spectral …

We report the first demonstration, to the best of our knowledge, of tunable and Q-switched
lasers based on diode-pumped Nd, Lu: CaF_2 disordered crystal. A continuous tuning …

A Yb-doped CaF 2 transparent ceramics was successfully fabricated by the hot-pressed
method and its laser characteristics were studied. A broad tuning performance and mode …

A diode-pumped femtosecond mode-locked Nd, La: CaF_2 disordered crystal laser was
reported for the first time. By appropriately choosing the Nd and La-doping concentration …

Both femtosecond and dual-wavelength picosecond operations of Nd, La: SrF 2 disordered
crystal laser have been demonstrated for the first time. In femtosecond operation, the laser …
