“…But this technique has got very high requirements for positioning and moving of the probe, compared to the comfortable interferometric inscription technique. First VBGs inscribed by a combination of fs-laser systems and interferometer are reported for LiF-crystals [3] and Ti:Sa-layers [10].…”

Interferometric inscription of volume Bragg gratings in a commercial high-refractive index glass (S-TIH53) by 400 nm femtosecond (fs) laser pulses

We demonstrate volume Bragg gratings inscribed in S-TIH53 glass. S-TIH53 is in the proper meaning not photosensitive; therefore we used a fs-laser system for the inscription process. The grating structure was formed in a Talbot interferometer and was investigated with help of the external Bragg reflection method. With this method we could measure the reflectivity profile and thereto the size of the grating. To ensure that the generated gratings are no surface or absorption gratings the probes were investigated by a microscope and absorption measurements and heating experiments were done.
