In this letter, we report the fabrication, modeling and characterization of an all-optically addressed spring patterned silicon-nitride deformable mirror microelectromechanical-systems device. Combinations of high-frequency ac and dc bias voltages are applied across the device. The experimental verified theoretical modeling for this device shows the mirror(More)
A 2- mu m Tm:YAG laser using a 1-mm diameter laser rod fabricated from material grown by the laser-heated pedestal growth technique has been characterized. Laser performance was found to be essentially identical to that obtained with bulk grown crystals. This demonstrates the usefulness of this technique for solid-state laser material evaluation and for the(More)
