Abstract
A diode pumped solid-state laser is disclosed having: a block of a lasing gain material with at least two optical surfaces and a cavity means positioned around the block to define a laser cavity which includes a mode shaping means to form an eliptical resonator mode between the optical faces within the block; a high aspect ratio pumping laser diode light source is positioned outside one of said optical faces; and a means to image the pumping light beam from said source to substantially match the elliptical resonator mode.
