Abstract

Ultrafast femtosecond laser systems have enabled many breakthroughs in the fields of science and technology. However due to the large spectral bandwidth necessary for creating short pulses, it is quite difficult to manipulate their transverse mode structure. Here we present successful femtosecond transverse mode conversion from the fundamental mode TEM00 to modes TEM01, TEM10, and TEM11 with the use of an achromatic phase mask based on diffractive optics. The femtosecond source had ∼12.8 nm of bandwidth and pulse duration of <100 fs.
