A modular amplifier composed of a series of crystals of varying parameters was developed, allowing flexible configurations. Changing from a configuration with uniform doping to one with diluted crystals at the front produced a 60% increase of output energy by reduction of parasitic oscillations, reaching 1.6J in single stage.
