Holographic Recording and Applications of Multiplexed Volume Bragg Gratings in Photo-Thermo-Refractive Glass

Volume Bragg grating (VBG) structures are capable of diffracting incident light into a single diffraction order with high efficiency given the Bragg condition is met. The Bragg condition depends on both the wavelength and angle of the incident light making VBGs useful for filtering and manipulating...

Description
Summary:Volume Bragg grating (VBG) structures are capable of diffracting incident light into a single diffraction order with high efficiency given the Bragg condition is met. The Bragg condition depends on both the wavelength and angle of the incident light making VBGs useful for filtering and manipulating both the wavelength and angular spectrum of a source. Recent research in the holographic recording of volume Bragg gratings in photo-thermo-refractive (PTR) glass has shown that these gratings are extremely useful components in high power laser systems for spectral narrowing, transverse mode control, beam combining, and pulses stretching and compression.
