Large linear micromirror array for UV femtosecond laser pulse shaping

We are fabricating a bulk-micromachined micromirror device for laser pulse shaping applications on femtosecond time scales. An array of micromirrors is used to individually retard or diminish certain laser frequencies spanning from the UV to the near-infrared. The individual mirrors are fixed by two springs on either side and can be tilted (amplitude modulation)or moved out-of plane (phase modulation) using asymmetrical or symmetrical vertical comb drives, respectively.
