27 May 1998 Closed-loop wavefront correction of Ti:sapphire chirped pulse amplification laser beam

We developed a technique to compensate the wavefront distortion of ultra-short pulse Chirped Pulse Amplification (CPA) laser by applying a closed loop wavefront control system consisting of a Shack-Hartmann type wavefront sensor and Bimorph type deformable mirror. As a result of the experiments both Root Mean Square (RMS) and Peak to Valley (P-V) value of the wavefront distortion were reduced to less than 1/5 of the original value, and it was shown that the brightness of laser beam was improved by about five times.
