Abstract
An all-solid-state laser comprising a slab (1) of gain medium, a diode laser pump system (3) configured in an end pumping geometry with the gain medium (1) and a heat sink thermally contacted to the gain medium (1) wherein the diode laser pump system (3) and the gain medium (1) are cooperably arranged so that in use a positive thermal lens is capable of being formed within the medium, the gain medium (1) having a thickness (d-d') made as small as possible while permitting the substantially unhindered passage through the slab of the laser mode established between the two mirrors (M1, M2).
