Abstract: We developed several prototypes of ceramic Nd:YAG slab lasers pumped by different laser diode stacks. Compactness, efficiency and ruggedness have been the principal design drivers. Nevertheless beam quality and insensitivity to diodes temperature have also been pursued. An edge-pumped device with less than 12% power variation over a 20°C temperature range has been demonstrated.
