A narrow band, green-red colour centre laser in LiF fabricated by femtosecond laser pulses

Recent advances in high‐intensity femtosecond (fs) laser pulses have made it possible to encode non‐erasable functional micro‐structures inside almost any type of photo‐insensitive transparent materials. We focus our attention on bulk lithium fluoride (LiF) because of its broad emission band from th...

Description
Summary:Recent advances in high‐intensity femtosecond (fs) laser pulses have made it possible to encode non‐erasable functional micro‐structures inside almost any type of photo‐insensitive transparent materials. We focus our attention on bulk lithium fluoride (LiF) because of its broad emission band from the green‐to‐red spectral range under excitation of a single absorption band at about 450 nm. Here a room temperature, visible laser action in LiF from a distributed‐feedback laser with embedded fine‐pitched gratings written by fs pulses and from a laser‐active colour centre laser with multilayer dielectric mirrors has been demonstrated.
