An efficient continuous wave (CW) laser-diode-pumped Nd-doped Ca(3)(NbGa)(2-x)Ga(3)O(12) (CNGG) laser operating at 935 nm is demonstrated by using a simple linear cavity for the first time to our knowledge. Output power up to 1.12 W is obtained, corresponding to a slope efficiency of 7.1% and an optical-to-optical efficiency of 5.7%. The laser operates with the fundamental transverse mode when the output power is as high as 800 mW. This laser provides a potential light source for differential absorption lidar in water vapor detection.

    ABSTRACT: We propose a novel technique for pumping neodymium vanadate crystal in 4F 3/2 → 4I 9/2 transition with polarized diode light. With a theoretical model on quasi-three-level neodymium vanadate lasers including excited state absorption and energy transfer upconversion effects, the improvement on the laser performance of polarized pumping is evaluated. A maximum output power of 4.8 W in Nd:GdVO4 912 nm laser is achieved with the incident pump power of 21.8 W, the maximum output power increases about 85% and the slope efficiency is enhanced to 1.5 times towards the unpolarized pumping under the same condition. This technique is especially suitable for quasi-three-level systems end pumped by high-brightness fiber coupled diode sources associated with short neodymium vanadate crystals.

    ABSTRACT: Continuous-wave (CW) and passively Q-switching laser performance of the Yb:CNGG and Yb:CLNGG disordered garnet crystals are compared. CW output powers of 6.3 and 7.5 W are generated from the Yb:CNGG and Yb:CLNGG lasers, with slope efficiencies measured to be 63 and 74 %, respectively. In passively Q-switched operation, the average output power reaches 2.0 and 3.1 W, with slope efficiencies of 56 and 65 %, for the Yb:CNGG and Yb:CLNGG lasers, respectively. Laser pulses of 9.5 ns in duration are generated with the two Yb lasers, with the highest pulse energy and peak power amounting to 166.7 μJ and 17.5 kW for the Yb:CNGG laser, and 133.0 μJ and 14.0 kW for the Yb:CLNGG laser. In respects of efficient laser operation and power scaling, the Yb:CLNGG proves to be advantageous over Yb:CNGG, whereas the Yb:CNGG is superior to Yb:CLNGG in energy storage capacity.

    ABSTRACT: Quasi-three-level solid-state lasers using trivalent rare earth ions are efficient sources in the near- and mid-infrared spectral regions. Their unique properties arise from special energy level structures in different host materials and highly efficient laser operation became possible with the availability of highly efficient high-brightness pump sources like laser diodes. This work will give an overview of quasi-three-level solid-state lasers emitting in the wavelength range 1–5μm. Recent research and advances in spectroscopic and laser results will be presented. In comparison to four-level lasers such as e.g. Nd3+ lasers at 1.06μm, quasi-three-level lasers show a much stronger influence of temperature on laser performance, mainly due to the thermally induced changes in the spectroscopic properties of the laser medium. Nevertheless, highly efficient lasers can be realized by direct diode pumping with high spatial and spectral brightness laser diodes. The population dynamics in the manifolds also play an important role and ion concentrations are used to minimize or maximize energy-transfer effects. These general topics will be addressed in Sect.1, in which basic aspects of quasi-three-level lasers and their description are discussed. Section2 deals with the general energy-level structure of trivalent rare earths in hosts, from which the most interesting ions and their transitions can be derived. These ions, Nd3+, Yb3+, Er3+, Tm3+ and Ho3+, are investigated in detail in Sect.3 in order of their emission wavelengths, focusing on their spectral properties and laser results in different laser architectures and host media. In Sect.4 the work is finally summarized.
