Fs-written Type-A volume Bragg gratings using a phase-mask and burst mode exposure
We report on the pioneering inscription of Type-A volume Bragg gratings (VBGs) using the phase-mask technique and a high-power (100 W average power) femtosecond laser operating in burst mode. We manage 3D volume material processing while decoupling the thermal load with nonlinear interaction thanks to the independent tuning of inter-burst and repetition rates. Finally, an 850 × 900 × 500 µm<sup>3</sup> grating was inscribed within 4.5 minutes, corresponding to a 4.1 mm<sup>3</sup>/h throughput and achieving ∼77% diffraction efficiency at 633 nm.
