Abstract
A light amplification device comprises a laser slab and optics for establishing an optical beam at the lasing wavelength. The beam travels inside the slab in a zig-zag path between two reflecting faces. The slab is also cooled through the reflecting faces. The slab is pumped through one or more pumping faces, each pumping face being distinct from the reflecting faces. Light from the pump is incident upon the slab in a direction that is transverse to the plane of propagation of the lasing wavelength beam. This arrangement separates the cooling interfaces from the pumping interfaces. Distortions in the beam due to thermal effects are largely averaged out by the zig-zag path. The device may function as either a laser or an optical amplifier.
