A dual cavity multifunction laser comprising a diode-pumped, contact cooled, slab laser head that supports two different length unstable resonators. The laser produces short (<8 ns), low energy 1 mum pulses or long (>15 ns), higher energy 1 mum pulses from the same laser system at different repetition rates, if desired. The output from each resonator can be separately optimized for different operating modes such as target designation and target profiling. The unstable resonators use independently optimized super Gaussian output couplers to generate high quality beams for each of the high and low pulse energy modes. The resonators also share a common bounce path to minimize intracavity losses and thermally induced birefringence for both resonators.
