Lithium strontium hexafluoroaluminate (LiSrAlF6, LiSAF) are excellent host materials for licaf tunable all-solid-state lasers in the UV region when doped with trivalent cerium(Ce:LiSAF). Ce 3+ -activated LiCaAlF 6 (LiCAF) and LiSrAlF 6 (LiSAF) single crystals are the most prospective active media for directly pumped ce licaf tunable laser transitions UV solid-state licaf tunable lasers. 2 nm, a pulse-to-pulse wavelength stability of 400 mJ • Pulse Duration 200 µs • Max. The fourth harmonic output beam was slightly focused into a 5 mm long Ce(2at. The final laser output can be tuned from approximately 283 to 310 nm with a bandwidth of 0.

In this work we present some laser experimental achievements obtained with the Ce:LiCaA1F6 (Ce:LiCAF) active medium. The Ce:LiCAF belongs to the family of ce licaf tunable laser transitions fluorides Ce3+ activated, which emit in the near UV with tunable emission. Both Ce:LiSAF and Ce:LiCAF exhibit strong energy absorption and broad tenability. The slabs would be tested in a transverse-pumping geometry to demonstrate moderate average powers over an extended tuning range in the UV. Ce:LiCAF (Ce:LiCaAlF₆) is a newly developed laser media suitable for tunable applications over a wavelength range of 720 to 840nm.

The development of Ce-activated LiSAF/LiCAF will provide the laser community with a crystal that can form the basis of the first, ce licaf tunable laser transitions all solid-state, tunable UV laser system. The IMR group pumped the laser with the fourth harmonic of a Q-switched Nd:YAG laser, focusing the horizontally-polarized pump beam through a 40-cm focal length lens to produce a 5 ce licaf tunable laser transitions mm-dia. 4 W in the IR and ce licaf tunable laser transitions 240 mW in the green at 1000 Hz. Ce:LiCAF is another tunable UV laser, with cerium. 1 nm, a pulse repetition rate of 1000 Hz, and a pulse width of 100 ns. A simpler and more efficient option is to use recently developed solid-state cerium-doped fluoride solid-state lasers, which produce tunable output directly in the 280- to 330-nm spectral region. The ce licaf tunable laser transitions gain spectra of Ce:LiSAF is in the transitions rangenm and is characteristic of the Ce3+ 5d1–4f1 interconfigurational transition. Ce:LiCAF licaf is another tunable UV laser, with cerium as the light emitting source, and lithium calcium aluminium fluoride as the crystalline host.

The transition from mode-locked to modulated CW operation is explored ce licaf tunable laser transitions experimentally for a Ce:LiCAF laser operating at 290 nm and pumped by a 78. The laser action was obtained by pumping Ce:LiCAF with frequency quadrupled Nd:YLF and Nd:YAG. The prospect of realizing laser action in trivalent rare-earth-doped crystals based on 5d⇒4f transitions was first proposed about 30 years ago. Other interesting properties enable them ce licaf tunable laser transitions to be used as scintillators and window materials. licaf The LiSAF crystal, when doped with cerium, behaves as an optical crystal that emits ce licaf tunable laser transitions lights of varying wavelengths, thus making it a tunable licaf laser. The resulting 263-nm beam then pumps a tunable cerium-doped lithium calcium aluminum fluoride (Ce:LiCAF) laser. More Ce Licaf Tunable Laser Transitions images.

The relatively large energy of the pump pulses resulted in a large beam cross-section in the crystal, thus allowing efficient quasicollinear longitudinal pumping. Of the two lasers, Ce:LiCAF has better tunability and spectroscopic properties. Using this crystal we realized. Due to the geterovalent activation nature of these crystals, crystal spectroscopic properties as well as their laser efficiency strongly depend on the actual crystal growth conditions.

A simpler and more efficient option is to use recently developed solid-state cerium-doped fluoride solid-state lasers, which produce tunable output directly in the 280- to 330-nm spectral region. 3 Short pulse generation from Ce:LiCAF laser. The laser was designed with the capability to translate the ce licaf tunable laser transitions Ce:LiCAF crystal resulting from damage issues, but additional modifica- tions have been made to the laser including the ability to translate the prisms mentioned above when they be- come damaged.
