Thermal Characterization, Crystal Field Analysis and In-Band Pumped Laser Performance of Er Doped NaY(WO4)2 Disordered Laser Crystals
Undoped and Er-doped NaY(WO4)2 disordered single crystals have been grown by the Czochralski technique. The specific heat and thermal conductivity (κ) of these crystals have been characterized from T = 4 K to 700 K and 360 K, respectively. It is shown that κ exhibits anisotropy characteristic of single crystals as well as a κ(T) behavior observed in glasses, with a saturation mean free phonon p...
متن کاملSpectroscopic properties and laser performance of resonantly-pumped cryo-cooled Er³⁺:GdVO₄.
We report a highly efficient cryo-cooled eye-safe laser operation of a resonantly-pumped (in-band) Er³⁺:GdVO₄ single crystal. The maximum continuous wave (CW) power of 10.3 W with 84% slope efficiency was achieved at 1598.7 with pumping at 1538.6 nm by a spectrally-narrowed Er-fiber laser. Under the 1529 nm resonant pumping by a commercially available diode bar stack operating in a quasi-CW (QC...
متن کاملDevelopment of 3.6 mW Er- doped C-band super fluorescent fiber source pumped at 980 nm
A 3.6mW single pass backward signal superfluorescent fiber source having a spectral width of 27.417nm was developed at a pump wavelength of 980.5nm and presented the experimental results along with non-flattened ASE spectrum. The fiber source could have direct applications in fiber sensors like fiber gyroscope or, in general, in any optical sensors in which a broad spectral band and high power ...

متن کاملEfficient 1 W continuous-wave diode-pumped Er,Yb:YAl3(BO3)4 laser.
We report the spectroscopy and high-power continuous-wave (CW) diode-pumped laser operation of Er:Yb:YAl3(BO3) crystal. Absorption and stimulated emission spectra, emission lifetimes, and efficiency of energy transfer from Yb3+ to Er3+ ions were determined. A CW Er:Yb:YAB laser emitting at 1602, 1555, and 1531 nm with output power as high as 1W and slope efficiency up to 35% was demonstrated.
