Lithium Fluoride (LiF) presents interesting optical properties and it has been proposed as an active optical material for colour centre (CC) lasers and amplifiers. The use of a grating to reduce the laser threshold and to narrow the line-width has also been demonstrated. More recently, LiF gained increased attention due to its unique characteristics as x-ray imaging detector for high resolution microscopy and for the development of CC lasers using gratings induced by high energy femtosecond laser pulses. We present a review of our recent work in the production of photonic structures, like photo-induced Bragg gratings and wave-guides either by laser CW illumination or by femtosecond laser irradiation. CW laser illuminated gratings were written in both coloured LiF crystals and films. Gratings and wave-guides are characterized using confocal microscopy, optical absorption and emission spectroscopy, near field scanning, scattering and insertion loss measurements. © 2011 Copyright Society of Photo-Optical Instrumentation Engineers (SPIE).
