Abstract: The present invention relates to a laser device and particularly a laser device having an elongated laser medium with a sidewall and an axis and capable when stimulated of having a population inversion established therein and an accompanying lasing condition, and a pair of pump sources at angle with respect to each other relative to the axis of the medium and positioned to pump energy uninteruptedly into the sides of the medium thereat. In the present construction the pump sources are rows of diode lasers and the construction includes an apparatus for dissipating the heat generated in the pump sources and in the medium. The angular orientation between the pump sources relative to the axis of the medium can vary from an acute angle to an obtuse angle and the device can have a reflective layer positioned on or adjacent to the medium at locations on the opposite side of the medium from the respective pump sources.

Abstract: A laser construction having a laser medium mounted on a mounting structure, and one or more diode laser pumped sources each formed by a plurality of laser diodes arranged in arrays and mounted on a mounting structure adjacent to the side of the laser medium in position such that when they are stimulated to lase their output radiation energy will be directed at the laser medium, insulation between the mounting structures for the laser medium and the laser diodes, and separate coolers for the mounting structures for the medium and for the pump sources including electrical connections thereto for controlling the temperature of the respective coolers. The invention also resides in such a structure wherein the medium is formed of separate medium portions, and the pump source on are mounted on separate mounting structures and are positioned separately excite the separate medium portions so as to produce separate laser output radiations therefrom.

Abstract: A package for the components of a laser device that includes an elongated laser medium, a pump source adjacent to one side of the laser medium and laser mirrors positioned in alignment with the optical axis of the laser medium, the package including a planar heat conducting structure including a base member with a cavity formed on one side and a platform at an intermediate location for supporting the laser elements, and a closure member for closing the cavity around the laser elements, and a multi-conductor connection cable mounted in the package having connections to the pump source and to a source of electrical energy.
