Abstract

An actively mode‐locked fiber laser (AMLFL) based on the hybrid gain of a dispersion‐shifted fiber (as the Raman gain medium) and an Erbium‐doped fiber (EDF) is introduced. The fiber Raman gain mechanism can effectively suppress the gain competition of an EDF, which usually results into the supermode noise in an actively mode‐locked EDF laser. We experimentally demonstrated a stable AMLFL with the repetition of about 5 GHz, in which the supermode noise is believed to be suppressed by employing the hybrid gain medium. © 2007 Wiley Periodicals, Inc.

We show what we believe is the first demonstration of an ytterbium-doped strictly all-fiber active mode-locking laser. The active control of the laser is based on in-fiber amplitude modulation at 11 MHz, which is achieved by using an all-fiber acoustooptic superlattice modulator driven by standing a

A passively mode-locked fiber ring laser is demonstrated using a 49 cm long bismuth oxide based erbium-doped fiber (Bi-EDF) and a fast semiconductor saturable absorber. Stable and clean short pulses are achieved because of these short and high nonlinear characteristics of the Bi-EDF. The laser opera

Supercontinuum generation with considerable flatness and low fluctuation is investigated in nonlinear fibers by amplification of pulsed seed signal of a stable mode locked bismuth oxide based erbium doped fiber laser. Spectral expansion from 980 to 1750 nm is obtained by 340 fs pulses at 1560 nm amp

## Abstract A cost‐effective and rugged actively mode‐locked erbium‐doped fiber laser operated at GHz repetition rate is demonstrated with the use of a Gunn oscillator as the RF source for driving the optical modulator. The high power from the Gunn oscillator eliminates the need of an RF driver. Th

## Abstract We present a single‐pass L‐band erbium doped fiber amplifier (EDFA) based on a large mode area (LMA) fiber. A single transverse mode is maintained through restricted mode launch. Pump light near 974 nm is sent into the core and has high spatial overlap with the signal beam, helping to p

## Abstract A simple microwave signal source is proposed by connecting two single‐longitudinal‐mode erbium‐doped distributed Bragg reflector fiber lasers in series. For using same pump LD, mutual injection locking of two fiber lasers is achieved. The two single‐longitudinal‐mode lasers have 0.048 n
