Programmable spatial beam shaping of a 100 kHz amplified femtosecond laser

Abstract : We present programmable spatial beam-shaping of 100-kHz, 4-µJ amplified femtosecond pulses in a focal plane using wavefront modulation. Phase distributions are determined by a numerical iterative procedure. A non-pixelated optically-addressed liquid crystal light valve is used as a programmable wavefront tayloring device. Top-hat, doughnut, square and triangle shapes with a 20-Μm size are obtained in a focal plane. The suitability for femtosecond laser machining is demonstrated.
