Abstract
Ultrafast femtosecond and high power CW laser systems are extensively used in the fields of science and technology. However, due to the wide emission spectra in ultrashort pulse and high power CW lasers, it is quite difficult to manipulate their transverse mode structure with conventional monochromatic phase masks. Here we present transverse mode conversion from the fundamental order TEM00 broadband lasers beams to different TEM and Laguerre-Gauss orders with the use of a broadband phase mask based on Volume Bragg Grating recorded in Photo-Thermo-Refractive (PTR) glass. The overall diffraction efficiency of the achromatic phase mask was 94%.
