Continuous tunable laser operation in both the 1.31 and 1.55 microm telecommunication windows in LiIn(Si/Ge)O4 olivines doped with trivalent chromium.
An ultrawide tuning range from 1160 to 1620 nm for LiInSiO(4) and from 1150 to 1600 nm for LiInGeO(4) crystals has been demonstrated. This is the widest bandwidth and the most near-infrared shifted wavelength range for laser operation ever demonstrated for the Cr(3+) ion. For what is believed to be the first time tunable laser operation was achieved for both the 1.33 and 1.55 microm telecommunication windows from a single optical center.
