Abstract

An edge-pumped solid state thin slab laser apparatus is disclosed that is power scalable to well over 150 W for either multimode or near single transverse mode operation. A slab thickness is selected that is small enough to minimize thermal effects for a straight through beam yet large enough to allow efficient direct coupling of pump light from high power diode array stacks while also keeping the gain to within manageable levels for pulsed operation. Cooling of the slab is provided by contact with metal blocks. The edge-pumped solid state thin slab laser provides a near-one dimensional temperature gradient and heat flow direction that is perpendicular to the laser signal plane of propagation. The width of the slab is selected so as to maximize pump absorption length for a given laser material and both one and two-sided pumping schemes can be accommodated by the basic slab laser platform.
