  ABSTRACT: Anisotropy of the nonlinear absorption of Co2+ ions in MgAl2O4 single crystal at the wavelengths of 1.35 and 1.54μm has been experimentally demonstrated. The experimental data are analyzed in the framework of a phenomenological model when the Co2+ ions are described as three sets of linear dipoles oriented along the crystallographic axes. Ground-state and excited state absorption cross-sections at 1.35 and 1.54μm are evaluated to be σgsa=(4.0±0.3)×10-19, σesa=(3.6±0.4)×10-20cm2 and σgsa=(5.1±0.3)×10-19, σesa=(4.6±0.4)×10-20cm2, respectively.

  ABSTRACT: The ground-state and excited-state absorption cross sections of a Cr5+:YVO4 single crystal were determined by the intensity-dependant transmission measurements to be(2.0±0.4)×10-18 cm2 and less than 0.1×10-18cm2 at 1.08μm, respectively. The bleaching relaxation time of the Cr5+:YVO4 crystal was estimated to be 3.5±1.5ns. Passive Q-switching of a diode-pumped Yb3+:YVO4 laser with the Cr5+:YVO4 saturable absorber was realized.

  ABSTRACT: We report on the spectroscopy and, for the first time to our knowledge, continuous-wave and Q-switched diode-pumped laser operation of Er,Yb:YVO4 crystal. Absorption and emission spectra of the crystal were determined. Lifetimes of Er3+ 4 I 13/2 and 4 I 11/2 levels that define laser performance of the crystal were measured and parameters of energy transfer between Yb3+ and Er3+ ions were estimated. cw output power of 115mW with slope efficiency of 5.4% was achieved at 1604nm. In the Q-switched mode an average output power of 81mW with slope efficiency of 3.5% and pulse duration of 150ns was obtained. In quasi-cw regime maximal peak power of 610mW with slope efficiency of 6.7% was demonstrated.

  ABSTRACT: We report the first demonstration, to our knowledge, of soft-aperture Kerr-lens mode locking in a diode-pumped femtosecond Yb3+:YVO4 laser. Near-transform-limited pulses as short as 61 fs are generated around a center wavelength of 1050 nm with an output power of 54 mW and a pulse repetition frequency of 104.5 MHz. This is, to our knowledge, the shortest pulse generated directly from an Yb laser having a crystalline host material. The femtosecond operation has a mode-locking threshold at an absorbed pump power of 190 mW. The nonlinear refractive indexes of the Yb3+:YVO4 crystal have been measured to be 19 x 10(-16) cm2/W and 15 x 10(-16) cm2/W for the sigma and pi polarizations, respectively, at 1080 nm.

  ABSTRACT: A diode-pumped Yb:YVO4 laser has been passively mode locked for the first time, to our knowledge. 120 fs pulses with an average output power of 300 mW and a peak power as high as 14.5 kW are obtained by use of a semiconductor saturable-absorber mirror for passive mode locking. The optical spectrum has a 10 nm bandwidth (full width at half-maximum) and is centered at 1021 nm.

  ABSTRACT: We report the efficient continuous-wave (CW) and Q-switched laser operation of a diode-pumped Yb:YVO4 laser. A CW output power of 1 W with a slope efficiency of 59% with respect to absorbed pump power was demonstrated. Passively Q-switched with a Cr4+:YAG saturable absorber, a Yb:YVO4 laser with Raman conversion was demonstrated. Q-switched 18.7- J pulses with a pulse duration of 17 ns and a peak power up to 1 kW were obtained at 1018-nm fundamental wavelength and 3.6- J pulses with a pulse duration of 6 ns and a peak power of about 0.6 kW were obtained at 1119.5-nm first-Stokes wavelength.

  ABSTRACT: In this work the optical spectroscopic and CW laser properties of Cr³⁺:BeAl₆O₁₀-crystal were experimentally investigated and compared with those of well-known laser medium - alexandrite (Cr³⁺:BeAl₂O₄). The research show that the absorption band is shifted to the red relative to the absorption band of alexandrite, allowing the use of diodes emitting at 670 nm for pumping. The emission cross-section of laser transition was estimated about 6.10^-20 cm², that on the order exceeds the analogous for alexandrite ( 0.7.10^-20 cm² ). The excited state lifetimes equal 18 μs at 77 K and 13.5 μs at room temperature.

  ABSTRACT: The EPR, optical absorption, luminescence spectra, and lasing characteristics of Cr3+, Ti3+, and Ni2+ ions in BeAl6O10 (beryllium hexaaluminate, BHA) crystals are studied. The spectroscopic data show that the BHA crystals have an orthorhombic structure with the space group Pbcm. The temperature dependence of luminescence lifetime of the excited state of Cr3+ ions (τ≈13×10−6 s at 300 K) is investigated. The energy gap between the 2E- and 4T2-levels of Cr3+ (∼236 cm−1) and the nonradiative relaxation activation energy (Ea≈1667 cm−1) are determined. High-efficient tunable radiation of a new BeAl6O10:Cr3+ laser crystal is demonstrated in the region of 0.78–0.92 μm at 300 K. It is shown that the doped BHA crystals are promising active media for tunable solid state lasers in the spectral regions of 0.7–1.0 μm (Cr3+) and 1.35–1.65 μm (Ni2+).
