In this paper we show the capability of volume phase holographic gratings recorded in photopolymerizable glasses for spectral pulse reshaping of ultrashort laser pulses originated in an Amplified Ti: Sapphire laser system and its second harmonic. Gratings with high laser induce damage threshold (LIDT) allowing wide spectral bandwidth operability satisfy these demands. We have performed LIDT testing in the photopolymerizable glass showing that the sample remains unaltered after more than 10 million pulses with 0,75 TW/cm^2 at 1 KHz repetition rate. Furthermore, it has been developed a theoretical model, as an extension of the Kogelnik's theory, providing key gratings design for bandwidth operability. The main features of the diffracted beams are in agreement with the model, showing that non-linear effects are negligible in this material up to the fluence threshold for laser induced damage. The high versatility of the grating design along with the excellent LIDT indicates that this material is a promising candidate for ultrashort laser pulses manipulations. eng Femtosecond spectral pulse shaping with holographic gratings recorded in photopolymerizable glasses journal article URL https://docta.ucm.es/bitstreams/e165b40e-4317-41a5-b5f0-a060fa5faa67/download File MD5 c00e89b7cbe8a48649fc54c7adb7389c 1207684 application/pdf Martinez-Matos08libre.pdf URL https://docta.ucm.es/bitstreams/13168e82-176f-49fc-80ff-3825c09fbcb8/download File MD5 d3001a7ef57900e2829e879da78c402c 41931 text/plain Martinez-Matos08libre.pdf.txt
