ABSTRACT:
An active mirror laser amplifier is described having a slab of Nd:glass which is optically pumped through the back face while the laser beam enters the slab through the front face and is reflected by a coating on the back face which reflects the laser beam while transmitting the pumping radiation. The laser beam is amplified as it moves toward the back face and after reflection from the back face as it propagates out and is emitted from the front face. The front face has an anti-reflection coating for the laser beam which coating reflects the pumping radiation. The storage efficiency of the laser is thereby increased and the temperature gradients in the slab are reduced (viz., the temperature profile is smoothed such that distortion of the slab is reduced and high power operation at high repetition rates of the laser pulse is obtainable).
