Abstract ：
Ce9.33(SiO4)6O2 (CSO) crystals were grown by the Czochralski (Cz) method. Rietveld refinement of XRD patterns confirmed the oxyapatite structure of CSO, XPS analysis revealed the valence of Ce ions in CSO crystals. Magnetization curve and temperature dependencies of the magnetic susceptibility were measured, paramagnetic behavior and magnetic anisotropy have been observed. Photoluminescence and Faraday rotation characteristics of the CSO crystal were investigated at room temperature. Verdet constants of CSO were about 1.6 times as large as those of TGG. Baesd on Van Vleck-Hebb theory, the effective transition wavelength and probability of CSO crystal were calculated and compared with other Ce3+-containing crystals. The absorption and magnetic circular dichroism (MCD) spectra of 4f -> 5d transitions in Ce3+ ions in CSO crystal were studied.

Abstract ：
A passively Q-switched (PQS) Yb3+:LuYLaVO4 laser based on a GaAs saturable absorber is reported. The nonlinear saturable absorption property of GaAs has been studied, the saturation fluence, modulation depth and non-saturation loss were characterized to be 3.3 MW/cm(2), 4.5% and 54.7%, respectively. In the PQS laser operation, the highest pulse repetition rate, shortest pulse width, largest single pulse energy and highest pulse peak power were measured to be 40 kHz, 4 ns, 16.7 mu J and 4.2 kW. The peak power achieved nearly three orders of magnitude improvement compared with the former Yb3+:LuYLaVO4 PQS lasers.

Abstract ：
ReS2 is emerging as a promising saturable absorber for solid-state lasers from visible to mid-infrared. In this paper, we report on a new approach of integrating a ReS2 saturable absorber into Yb:Lu0.74Y0.23La0.01VO4 crystal based Q-switched laser. Under maximum pump power, the highest pulse energy at 1.03 mu m wavelength was measured as 5.3 mu J, which is one order of magnitude higher compared with the previously reported 1 mu m solid-state passively Q-switched lasers based on ReS2 saturable absorber.

Abstract ：
Due to the advantages of ultra-broad bandwidth absorption and easy fabrication, passively mode-locked ultrashort lasers using two-dimensional (2D) materials as saturable absorbers (SA) have attracted extensive attention in recent years. In this experiment, the structure and light absorption properties of 2D nickel-cobalt layered double metal hydroxide (NiCo-LDH) nanosheets are characterized. The nonlinear absorption coefficient of NiCo-LDH are measured by Z-scan method to be -1.1 cm/GW. Using the NiCo-LDH SA, passively mode-locking is realized in a Nd:YVO4 bulk laser near 1 μm, a Nd:Y0.15V0.85O4 bulk laser near 1.3 μm and a Tm:YAG ceramic bulk laser near 2 μm. In the 1 μm passively mode-locking experiment, a continuous wave mode-locking (CWML) laser is obtained at 1065.92 nm with a repetition rate of 69 MHz and a pulse width of 18.0 ps. To our knowledge, this is the first time a CWML laser has been obtained using a layered double hydroxides (LDHs) SA. In addition, Q-switched mode-locking (QML) lasers are obtained based on NiCo-LDH SA at 1.3 μm and 2 μm. The experiments demonstrate that NiCo-LDH mode locking is a very promising practical technique for directly generating ultrashort pulsed laser from a laser oscillator. © 2022 SPIE.

Abstract ：
CaDyAlO4 (CDA) crystals with dimensions of Phi 25 x 28 mm3 were grown by the Czochralski method. The presence of a small amount of oxygen in the growth atmosphere will cause the coloration of CDA crystal, and correspondingly reduce the transmittance in the range of 400-730 nm. Rietveld structural refinement of XRD patterns revealed a slight difference in the unit cell parameters of the brown and yellow-green CDA crystals. The angular and temperature dependencies of the magnetic susceptibility were measured, indicating that CDA crystal has remarkable magnetic anisotropy and abnormal magnetic behavior in the a and c direction below 150 K. Faraday rotation characteristics of CDA crystal were investigated at room temperature. Verdet constant of CDA at 500-700 nm band is about 1.1 times as large as that of TGG, but only 0.69 fold of that for isostructural CaTbAlO4 (CTA). Based on the Van Vleck-Hebb theory, the effective transition wavelength and probability of three crystals were calculated and compared. The absorption and magnetic circular dichroism spectra (MCD) of 4f-4f transitions in Dy3+ ions in CDA were studied.

Abstract ：
A passively-Q-switched Yb:Lu1-x-yYxLayVO4 laser based on a two-dimension (2D) molybdenum ditelluride (MoTe2) saturable absorber (SA) is reported for the first time to the best of our knowledge. High quality few layered 2D MoTe2 nanosheets were fabricated by liquid phase exfoliation (LPE) method and used as the SA, whose saturable absorption properties around 1.0 mu m were characterized with a saturation fluence of 3.02 mu J/cm(2) and a modulation depth of 8.3%. In the passively Q-switched laser operation, the shortest pulse width of 500 ns was obtained with an average output power of 0.33 W at a pulse repetition rate of 117 kHz, corresponding to the maximum single pulse energy of 2.8 mu J and the peak power of 5.6 W.

Abstract ：
A diode end-pumped acousto-optic Q-switched Nd:YVO4/LuVO4 Raman laser is demonstrated. Both YVO4 and LuVO4 can work as Raman gain, and slightly different active vibration modes of both crystals can result in different first-Stokes wavelengths. The output characteristic as the Raman competition between YVO4 and LuVO4 crystals for the laser systems with both shared cavity and coupled cavity is experimentally investigated. For the shared cavity, simultaneous Raman conversion in both YVO4 and LuVO4 crystals is achieved with dual-wavelength emission at 1175.8 and 1177.1 nm. The maximum output power of 1.03 W and the conversion efficiency of 10.3% are obtained. The 0.84 W single first Stokes wavelength at 1177.1 nm with LuVO4 Raman conversion is achieved with the coupled cavity. The results show that the coupled cavity with short Raman cavity can obtain a narrow pulse width. The separated laser crystal and Raman gain media with different vanadates in shared cavity have advantages in achieving dual-wavelength lasers with small frequency intervals.

Abstract ：
We report on the crystal growth, structure, Raman and optical spectroscopy of novel "mixed" tetragonal vanadates, Yb:Lu1-x-yYxLayVO4. Optical absorption, stimulated-emission, and gain cross-section spectra of Yb3+ are determined for pi and sigma polarizations. For a Yb: Lu0.74Y0.23La0.01VO4 crystal, the absorption bandwidth is > 10 nm, the sigma(SE) is 1.1 x 10(-20) cm(2) at 1013 nm, the gain bandwidth is > 40 nm (for p-polarization), and the radiative lifetime of the F-2(5/2) state is similar to 305 mu s. The Stark splitting of the Yb3+ multiplets is determined using low-temperature (6 K) spectroscopy. A diode-pumped alpha-cut 2 at.% Yb: Lu0.74Y0.23La0.01VO4 laser generated 5.0 W at 1044 nm with a slope efficiency of 43%. The developed materials are promising for sub-100 fs mode-locked lasers at similar to 1 mu m. (C) 2018 Optical Society of America under the terms of the OSA Open Access Publishing Agreement
