Volume-Bragg-Gratings were inscribed in glass by using a femtosecond-pulses to overcome the limitation of photosensitive materials. For inscription a wavelength of 400 nm was chosen to fabricate first order gratings. The fabrication itself was done holographically using a Talbot interferometer. The grating structure was analyzed by external Bragg reflection. Further investigations on the grating like absorption measurements, microscopic imaging and heating experiments were done.
