Ultrashort pulse written, high order volume Bragg gratings in fused silica for VIS and UV laser diode stabilization

Ultrashort laser pulses and the phase mask scanning technique enable the inscription of VBGs in fused silica with low intrinsic absorption. These VBGs have improved the performance of stabilized laser diodes in high power applications in the NIR. To extend their application to the low VIS to near UV wavelength range, we are investigating their performance at higher Bragg orders. The dependence on inscription parameters and grating period is analysed.
