We have developed a slab-type Nd:YAG gain module based on the techniques of conduction cooling and end pumping. The Nd:YAG slab is end-capped on both ends by undoped pure YAG and is pumped through the end-caps by stacked arrays of laser diode bars. T

Wavefront sensing using a Shack-Hartmann sensor has been widely used for estimating wavefront errors or distortions. The sensor combines the local slopes, which are estimated from the centroids of each lenslet image, to give the overall wavefront rec

To design a laser beam director (LBD), we considered the ritchey chretien system with a hyperbolic mirror surface. The aperture sizes of the designed primary mirror and secondary mirror were 800 mm and 120 mm, respectively, and the obstruction ratio
