Seminarium Optyczne

Material processing with ultrashort pulsed lasers is effective for a variety of high precision 3D fabrication tasks. In this talk, I will present advances using adaptive optics – deformable mirrors and liquid crystal spatial light modulators – to bring extra degrees of control to the optical system. Adaptive optic elements offer potential for beam shaping, aberration correction and parallelization leading to improved device fabrication in a range of materials. Applications include photonic circuits in glass and nitrogen vacancy colour centre creation in diamond. Furthermore, I will show that using adaptive optics with ultrashort pulses not only modifies the phase front of the incident light, but can additionally be used to shape the temporal intensity profile of the pulse with spatial resolution.
