- Inscription of first-order sapphire Bragg gratings using 400 nm femtosecond laser radiation
Inscription of first-order sapphire Bragg gratings using 400 nm femtosecond laser radiation
in: Optics Express (2013)
The paper describes the implementation of fiber Bragg gratings inscribed by femtosecond laser pulses with a wavelength of 400 nm. The use of a Talbot interferometer for the inscription process makes multiplexing practicable. We demonstrate the functionality of a three-grating multiplexing sensor and the temperature stability up to 1200 °C for a single first-order Bragg grating.
