This patent describes an improved unitary laser. It comprises, in combination, a transparent, thermally conductive solid housing comprising a pair of semi-cylindrical sections joined at one surface to be movable between a first open position and a second closed position; a laser medium that has two opposite ends and is embedded over its total length in a first cavity in the housing which is defined by the housing, when the housing is in the second, closed position; a pump lamp for exciting the laser medium having an envelope and internal electrodes which pump lamp is embedded over the whole length of its arc and over a substantial length of each of its elecrode regions in a second cavity in the housing, such that the external surface of the pump lamp and the internal surface of the second cavity are mated with a clearance there between of not more than about 0.1 millimeters; and reflector means adjacement to the opposite ends of the laser medium that define an optical resonant cavity and support coherent radiation laser emitted by the laser medium.
