TL;DR: The Nd:YAG resonator as mentioned in this paper is able to deliver beams with various spatial profiles such as flat-topped super-Gaussian and square-shaped beams, but it is not suitable for beamforming with an intracavity optically addressed liquid-crystal spatial modulator.
Abstract: We present a new beam-shaping technique with an intracavity optically addressed liquid-crystal spatial light modulator. The Nd:YAG resonator is able to deliver beams with various spatial profiles such as flat-topped super-Gaussian and square-shaped beams.

TL;DR: Experimental measurements of the thermal aberrations of a high power diode-pumped Nd:YAG rod laser head are presented, and it is shown that residual aberrages are mostly astigmatism and spherical aberration.
Abstract: Summary form only given. The availability high power laser diodes permits to pump with high efficiency a large volume of gain medium, and it allows in principle to extract more power from laser cavities having a large mode size. However, the larger the mode, the more important the influence of the thermal aberrations. This motivated recent researches on homogeneous pumping chambers to reduce these aberrations. We present experimental measurements of the thermal aberrations of a high power diode-pumped Nd:YAG rod laser head, and show that residual aberrations are mostly astigmatism and spherical aberration. In order to determine the influence of these aberrations, we completely modeled a standard cavity, including thermal aberrations and gain saturation.

TL;DR: In this paper, the Nd:YAG laser rod resonator design, and show CW and Q-switching operation external frequency doubling is achieved using a Type II flux grown KTiOPO/sub 4/ crystal.
Abstract: Summary form only given Q-switched solid-state oscillators are attractive due to their compactness, stability and high efficiency High average power frequency conversion of these systems is commonly performed intracavity Owing to pulse peak powers up to 500 kW the developed system is suitable for external high average power frequency doubling We present the Nd:YAG laser rod resonator design, and show CW and Q-switching operation External frequency doubling is achieved using a Type II flux grown KTiOPO/sub 4/ crystal
