We report on a tunable neodymium-doped fiber laser using an intracavity lithium niobate-integrated tuner. The device is a low-voltage asymmetric LiNbO 3 Mach-Zehnder interferometer working as a tunable spectral filter. Laser emission occurs simultaneously at two wavelengths, lambda 0 = 1088 nm and lambda 2 = 544 nm, due to the nonlinear properties of the crystal. The lasing wavelengths are tuned over ranges of 12 nm in the infrared and 6 nm in the green region with tuning rates of 0.25 and 0.12 nm/V, respectively. Copyright 1998 Academic Press.
