Abstract: A slab module for a face-pumped laser includes a box frame having top and bottom walls and opposite end walls defining a central slab chamber therein. The end walls have central access holes for receiving opposite ends of a laser slab positionable in the slab chamber. The frame also includes opposite side pockets which join with the slab chamber. The pockets are configured for receiving laser pumping modules for pumping the laser slab, with the modules including diode laser arrays in an exemplary embodiment.

Abstract: A modular slab assembly for a face-pumped laser includes a slab module having top and bottom reflector segments, with first and second inner end caps joined thereto. A plurality of alignment keys are disposed between the inner end caps and the reflector segments for maintaining alignment therebetween, with the inner end caps being removably fastened to the reflector segments. The inner end caps have central apertures for supporting a slab tube, with a laser slab being disposed through the tube and supported at its ends by outer end caps removably fixedly joined to respective ones of the inner end caps. A pair of removable lamp modules are disposed on opposite sides of the slab module and contain lamps for exciting the laser slab.

Abstract: This invention relates to a positioning, compression and storage device for modular face-pumped slab laser heads of the type that are constructed of individual components, which are rigidly attached together, in order to form an integral structure. Such structures of this type, generally, allow face-pumped slab laser head components to be assembled and stored easily and quickly.

Abstract: This invention relates to lasers which produce a high average power. Such structures of this type, generally, produce the high average power intensity having a high peak intensity at a wavelength near 530 nm.

Abstract: A substantially rectangular slab of laser material has a pair of opposing concave edge faces to reduce parasitic oscillations. The concavities can be curved in either the transverse or longitudinal directions or both, i.e., they are toroidal sections. The slab can be Nd:YAG. Brewster ends and chamfered corners can be provided for the slab as well as tapered portions for the concavities. In a laser, the concave portions have a length slightly greater than that of the pump lamps. A pair of siderails are over the concave portions to reduce optical distortion.
