Multiwavelength YB‐doped fiber ring laser based on a Mach‐Zehnder interferometer

We proposed and demonstrated a room-temperature multiwavelength Yb-doped fiber ring laser with high stability based on a Mach-Zehnder interferometer by exploiting spatial hole burning and polarization hole burning effects, from which stable eight lasing wavelengths is obtained. The number of the lasing wavelengths (eight) is the most to our knowledge, and the wavelength spacing is 1.1 nm. Triple-, and dual-wavelength operation with the wavelength spacing of 1.1 nm or its integral multiples have been obtained by adjusting the intracavity polarization controllers. © 2008 Wiley Periodicals, Inc.
