By combining a lumped amplifier and a coupler with high output ratio, we present a passively mode‐locked Er 3+ ‐doped fiber laser with ring cavity, which directly produces 1.2‐nJ pulses with a rectangle‐shaped spectrum of 19.4 nm. To our knowledge, they are the highest pulse‐energy and broadest spectral width obtained directly from Er 3+ ‐doped fiber lasers without using the dispersion‐compensation technique. © 2005 Wiley Periodicals, Inc.
