The present invention relates to a specific holding structure of a slab geometry crystal for a total internal reflection, slab geometry laser (otherwise known as face pumped laser) device. Both sides of the crystal are held by side rails, and on both longitudinal end portions of the crystal o-ring backing flanges and box-shaped end pieces, respectively, are put on. Furthermore, an o-ring is put in between the end piece and the o-ring backing flange on each end portion of the crystal, and it is compressed to seal the crystal. This o-ring can be made of translucent elastomer. Accordingly, the slab geometry laser device that is compact and easy to remove from, or place into the pump station is provided.
