We report on the inscription of fiber Bragg gratings using ultrashort laser pulses and the phase mask technique. By deforming the wavefront of the inscription laser a tuned reflection wavelength as well as broadband chirped gratings could be realized. A theoretical analysis and experimental results will be discussed.
