A method utilizing an unprocessed cleavage microchip as the solid-state laser gain medium is proposed. Pumped by a Ti:sapphire laser at 871 nm, 1060 nm continuous-wave laser emission with slope efficiency of 23% has been achieved in an unprocessed microchip directly obtained from a cleavage Nd3+:LaB3O6 crystal. Based on this method, it is possible to avoid the difficulty of the microchip gain medium processing and largely lower the cost of solid-state lasers.
