Longitudinally diode-pumped Nd:YAG double-clad planar waveguide laser.
We report the demonstration of a near-diffraction-limited, compact, diode-end-pumped double-clad planar waveguide Nd:YAG laser. Efficient laser operation was achieved for the three dominant Nd(3+) transitions, at 1.064, 0.946, and 1.32microm , with TE polarized output powers of 1.33, 0.57, and 0.33 W for the available output couplers. The output beam from the monolithic plane-plane laser cavity...
متن کاملHigh-efficiency diode-pumped Tm:YAG ceramic laser
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% respect...

متن کاملCompact diode-pumped passively Q-switched tunable Er-Yb double-clad fiber laser.
Efficient repetitive passive Q switching of a cladding-pumped Er-Yb fiber laser has been demonstrated by use of an external-cavity configuration containing a Co(2+): ZnS crystal as a saturable absorber. Energies of as much as 60muJ in pulses of durations as short as 3.5 ns (FWHM), corresponding to a peak power of >10kW, have been generated, and the maximum slope efficiency with respect to the a...
متن کاملModeling of High-Power Continuous-Wave Tm:YAG Side-Pumped Double-Clad Waveguide Lasers
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 ...
