In this paper a LD end-pumped Nd:YAG ceramic microchip laser passively Q-switched by Cr4+:YAG absorber is demonstrated to generate axisymmetrically polarized pulse. The reason to employ the end-pumped microchip laser lies in the fact that such cavity configuration is beneficial carrier both for producing energetic Q-switched pulse and also the axisymmetrical polarization. The Cr4+:YAG crystal absorber...
In this paper, we present the experimental demonstration of a linearly polarized continuous-wave microchip laser based on cubic Yb:YAG crystal selected by the crystalline orientations in the (111) plane when the light propagates along the [111] direction. The effect of pump power induced birefringence and depolarization on the crystalline orientation selected linearly polarized states of continuous-wave...
The microchip laser performance of Yb:YAG crystals doped with different ytterbium concentrations (10, 15, and 20 at.%) has been investigated at ambient temperature. Efficient laser oscillation for 1-mm-thick YAG doped with 10 at.% Yb3+ ions was achieved at 1030 and 1049 nm with slope efficiencies of 85 and 81%, correspondingly.
Here we report on the high peak power laser performance of Yb:YAG/Cr:YAG all-ceramic miniature laser by using low initial transmission of the Cr4+:YAG and high transmission of the output coupler.
