High-efficiency diode-pumped Tm:YAG ceramic laser
نویسندگان
چکیده
A high efficient Tm:YAG ceramic laser at 2007 nm pumped by a diode laser was demonstrated. The laser performances with Tm doping concentrations of 4 at.% and 6 at.% were comparatively analyzed. The continuous-wave (CW) laser powers up to 2.11 W and 1.68 W have been obtained for Tm:YAG ceramics at 6 at.% and 4 at.% doping levels, corresponding to the slope efficiencies of 43.6% and 53.8% respectively.

Diode pumped highly efficient Yb : Lu 3 Al 5 O 12 ceramic laser
A diode pumped ytterbium-doped lutetium aluminum garnet (Yb:LuAG) ceramic laser is reported for the first time to our knowledge. Using the solid state reactive vacuum sintering technique we have successfully fabricated high optical quality Yb:LuAG ceramics. We show that even with an uncoated Yb:LuAG ceramic sample a maximum output power of 7 W could be achieved under 13 W absorbed pump power, a...

We experimentally demonstrated the manipulation of 2 μm linearly polarized states in a diode-pumped YAG/Tm:YAG/YAG laser with high polarization extinction ratio of 28 dB for the very first time to the best of our knowledge. A stable linearly polarized state of 2 μm was achieved without using any specific intracavity optical polarization-selected elements. The unexpected phenomenon of tunable li...

A plane-wave model accounting for cross-relaxation, upconversion, ground-state depletion, and gain saturation in continuous-wave laser systems is applied to side-pumped Tm:YAG double-clad planar waveguides. The temperature profile due to high-power pumping, and the delivery and absorption efficiencies of proximity-coupled diode bars, are also calculated. The theoretical performance is found to ...
متن کاملHighly efficient room-temperature Yb:YAG ceramic laser and regenerative amplifier.
A room-temperature, diode-pumped, pulsed Yb:YAG ceramic free-running laser with a 78% slope efficiency has been demonstrated. It has been shown that fine tuning of the mode diameter to the diameter of the pumped volume with a ratio of the pump to the mode diameter of 0.6 is important for achieving maximum laser efficiency with a Gaussian-like beam profile. A regenerative Yb:YAG ceramic amplifie...

Ceramic laser media fabricated by vacuum sintering (Ikesue et al., 1995), (Ikesue et al., 1996), and nanocrystalline (Lu et al., 2000) technology are very attractive materials because they have several remarkable advantages compared with single crystal laser materials. Ceramic samples with a large size can be easily fabricated, whereas this is extremely difficult for single crystals; multiplaye...
