Abstract

In this study, a continuously tunable Er‐doped fiber laser based on a double‐clad Er^3+^/Yb^3+^ co‐doped fiber amplifier is demonstrated. By using the nonlinear polarization rotation technique, the tunable laser operating can be an all‐fiber structure and have tuning range, power variation, and laser line width of 15 nm, 0.37 dBm, and less than 0.06 nm, respectively. By using an Er^3+^/Yb^3+^ co‐doped fiber amplifier, the amplified spontaneous emission intensity can be more than 40 dBm suppressed over the tunable range, and the power conversion efficiency is about 10.5%. © 2008 Wiley Periodicals, Inc.

## Abstract We report on a all‐fiber actively Q‐switched laser based on a Mach‐Zehnder interferometer (MZI). One of the arms of the MZI is bonded on a piezoelectric transducer (PZT). The path length difference between those two arms will change when a RF electric signal is applied drives the PZT, a

We report wide wavelength tuning in a double-clad ytterbium-doped fiber laser. The laser cavity consists of an array of broadband high-reflection fiber Bragg gratings and a bulk grating as output coupler and wavelength selection element. The proposed fiber laser configuration combines low intra-cavi
