Tunable LiF:F/sub 2//sup -/ color center laser with an intracavity integrated-optic output coupler

Fabrication and characterization of optical waveguides on LiF by ion beam irradiation

“…1 In bulk form, several amplification effects or laser devices based on colored LiF working at room temperature have already been reported in literature. [2][3][4][5][6][7] For these reasons, in recent years we have been concentrating our efforts in the development of planar optical guiding structures capable of replicating bulk results in integrated optics devices [8][9][10][11] which would provide obvious advantages in terms of compactness, ruggedness, integration with other optoelectronic devices. Our work has been mainly focused on F 2 and F 3 + color centers, whose luminescence spectrum as measured on one of our samples, is shown in Figure 1.…”
