Programmable spectral phase control of femtosecond pulses by use of adaptive optics and real-time pulse measurement
The authors describe a programmable spectral-phase, pulse-shaping system for femtosecond pulses based on the 19-channel linear deformable mirror from OKO Technologies. Accurate spectral phase design as well as pulse intensity modulation was achieved with direct control of the mirror surface by use of a negative-feedback, mirror-surface control mode. Convergence to the chosen spectral-phase design was typically achieved within several seconds. J. Opt. Soc. Am. B, 21, 4, 833–843 (2004) Author(s): J. Garduño-Mejía, A. H. Greenaway, D. T.

Spherical aberration correction for optical tweezers
In typical optical tweezers experiments the quality of the trap deteriorates due to optical aberrations caused by the refractive index mismatch at the glass–water interface when trapping deep inside a sample or out of the imaging plane. The authors correct these aberrations using a 37-channel micromachined membrane deformable mirror from OKO Technologies. Optics Communications 236, 145–150 (2004) Author(s): E. Theofanidou, L.
