Membrane and piezoelectric deformable mirrors for ultrafast
pulse control. These mirrors are usually used in a stretcher for
selective control of the delays of chosen spectral components.
Linear PDM for pulse compression
The linear piezoelectric deformable mirror for femtosecond pulse shaping has 10x50 mm active area, controlled by two
rows of 10 actuators each. The actuator pitch is 5 mm. The maximum surface deflection is 6 um, the profile difference
between the adjacent actuators can reach 3µm. The initial figure is slightly spherical. The mirror can be custom coated
with low-dispersion dielectrics and metal-dielectric coatings. The mirror can be supplied with a complete set of control
electronics, including 20-ch 400 V amplifier unit and a 20 (40)-ch USB DAC unit (or a 24-ch 8-bit PCI DAC card) for
interfacing to a PC. Full technical description can be downloaded from our website www.standa.lt .
Linear MMDM for pulse compression
The linear membrane DM represents an attractive alternative to LC wavefront correctors for femtosecond pulse
compression and precise control and optimization of the temporal/spectral pulse parameters. They feature very low
dispersion, negligible power consumption, high optical quality which is usually better than 2 fringes over the whole
aperture, fast response and large correction range. These mirrors can be coated with high-reflective dielectric coatings
to be used in lasers at power levels of up to 500W CW. Negligible hysteresis. The linear MMDM are available with 19
and 38 (2x19) actuator structures, with 11x39 mm membrane.
