“…The energy level scheme of Pm 3+ allows for visible fluorescence, but due to the lack of stable promethium isotopes it is of low practical use for laser applications. Furthermore, Nd 3+ , Eu 3+ and Tm 3+ do exhibit a variety of transitions in the visible and even allowed for visible laser operation [19][20][21].…”

The rise of semiconductor-based pump sources such as In x Ga 1-x N-laser diodes or frequency-doubled optically pumped semiconductor lasers with emission wavelengths in the blue encourages a revisitation of the rare-earth ions Pr 3+ , Sm 3+ , Tb 3+ , Dy 3+ , Ho 3+ and Er 3+ with respect to their properties as active ions in crystalline solid-state laser materials with direct emission in the visible spectral range. Nowadays, some of these blue-pumped visible lasers compete with Nd 3+ -lasers in terms of efficiency and direct lasing at various colors from the cyan-blue to the deep red can be addressed in very simple and compact laser setups. This paper highlights the spectroscopic properties of suitable rare-earth ions for visible lasing and reviews the latest progress in the field of blue-pumped visible rare-earth doped solid-state lasers.

“…It should be noted, however, that neodymium possesses also interesting emission and lasing properties in the UV spectral range, associated with the 4 D 3/2 and 2 P 3/2 energy levels. Up-converted UV lasing originating from these bands was for the first time reported in 1988 in fluoride crystals (at 380 nm in Nd:LaF 3 and at 413 nm in LiYF 4 ) at cryogenic temperatures [4,5]. Also the photon-avalanche process in Nd:LiYF 4 has been reported resulting in violet lasing at 413 nm under 603 nm pumping [6].…”

In this work the short-wavelength emission properties are investigated for the highest observed 4f metastable energy level 2 F(2) 5/2 of Nd 3+ ions in fluorozirconate ZBLAN glass. Various dopant concentrations, ambient temperatures and excitation conditions have been considered throughout the study. Distinct spectral features were observed under pulsed and cw excitation at 514 nm. In particular, pulsed pumping enabled recording of 2 F(2) 5/2 emission spectra, not observable under CW excitation, as well as the level's fluorescence decay dynamics and its evolution with temperature and dopant concentration. According to the best of the authors' knowledge, neither the fluorescence lifetime of 2 F(2) 5/2 of Nd 3+ in ZBLAN, nor its concentration dependent evolution were reported before.

“…Solid-state lasers based on frequency upconversion phenomena in rare-earth ͑RE͒ doped materials [1][2][3][4][5][6][7] are promising violet/blue light sources for applications such as high-density data storage, displays, contaminant detection, and biological research. 8 A common procedure to investigate new upconversion lasers is to choose a convenient host with a low energy phonon spectrum which allows a larger lifetime of RE metastable states and large luminescence efficiency.…”

Articles you may be interested inWe report optical gain at 382 and 414 nm from Nd 3ϩ -doped fluroindate glasses after excitation with lasers operating either at 583 or 532 nm. Stimulated emission due to a frequency upconversion process results in increase of the emitted violet and blue light intensity and emission line narrowing. Large optical gain is measured by pump-probe spectroscopy using samples with various Nd 3ϩ concentrations.
