High intensity laser beam wavefront diagnostics and correction at the Advanced Laser Light Source facility

The Advanced Laser Light Source (ALLS) is a Canadian facility consisting of several high intensity laser systems based on Ti:Sapphire technology. These lasers deliver 25-35 fs laser pulse time duration, from 1 mJ up to 5 J energy per pulse, high repetition rate from 10 Hz to 5 kHz, and up to 200 TW of instantaneous power or 50 W of average power. The aim of this facility is, first to produce laser based radiation source ranging from THz up to the hard X-ray and acceleration of high energy particles; second to develop and optimize such laser based sources and study their potential applications in field such as biomedical imaging, time resolved X-ray spectroscopy or molecular imaging. We will present the laser beams wavefront diagnostics and the correction methods by means of deformable mirrors used at ALLS.
