Fabrication of reflective volume gratings in pulsed-laser-deposition Ti:sapphire waveguides with UV femtosecond-laser pulses
Highly reflective volume Bragg gratings (R~80%) were written in Ti:sapphire planar and channel waveguides fabricated via pulsed-laser deposition (PLD) by exposure to UV (266 nm) femtosecond laser irradiation through suitable phase masks. Large photo-induced refractive index modulations of up to ~1×1...
