Stimulated emission in multiply doped Ho³⁺:YLF and YAG - A comparison

Synthesis and Optical Properties of KYF4/Yb, Er Nanocrystals, and their Surface Modification with Undoped KYF4

“…The low phonon energies of these materials reduce thermal lensing effects under strong pumping conditions and make these materials particularly suitable for IR transitions. [13,14] The spectroscopic properties of Er 3þ , Tm 3þ , and Ho 3þ ions doped into singlecrystalline KYF 4 were investigated by Khaidukov and Bouffard [15] and by Sani et al, [16] respectively. The thermoluminescence of KYF 4 /Tm 3þ was investigated by Coeck et al [17] Aleonard and co-workers synthesized pure and rare-earth-doped crystalline powders of KYF 4 or KY 3 F 10 by hydrothermal means.…”

Excited-state dynamics and energy transfers in (Ca,Zr)-substituted Gd3Ga5O12single crystals doped with Cr3+and Tm3+ions

“…Most often, the fluorescence of the Ho3' ions is sensitized by erbium and thulium ions in fluorides and also by chromium ions in garnets. Many continuous-wave (cw) and Qswitched laser operations have been proved in several holmium-doped crystals at cryogenic as well as room temperature [1][2][3][4][5][6] and recently more especially with laser diode pumping [7]. It wasshownrecentlythat laserradiationaround2pmcanalsobeobtained from the )F4-+ 3HH, transition of Tm3t in garnets [S, 91.…”

Photoluminescence in Er(TTA)3(Phen) Thin Film

“…Yb 3 is added as a sensitizer for Er 3 lasers. In LiYF 4 lasing action at several infrared wavelengths namely 0.85, 1.5 and 2.7 mm was reported by Chicklis et al [12] and Kintz et al [13]. Emission properties, oscillator strengths and laser parameters of Er 3 in LiYF 4 have been studied by Hubert et al [1].…”
