The central wavelength of the incident pulsed-laser beam is 0.8 m, and the corresponding circular frequency is 0 2.35455 = 10 15 radrs. We define ⌬ as the full width at half maximum of the incident pulse, and z as the Talbot distance t of the central frequency light. First, we will calculate the int

Abstract
Variation of laser signal‐to‐noise ratio (SNR) in an erbium‐doped fiber‐ring laser system subject to external injection is presented. Laser SNR is found to be dependent not only on the injected power, but also on the amplification characteristic over the entire amplified spontaneous emission (ASE) bandwidth. Both laser SNR and injected power as a function of the signal detuning show an inverse relation with the ASE spectral profile. © 2002 Wiley Periodicals, Inc.

## Abstract Multiple mode instabilities in erbium‐doped fiber laser are undesirable due to the large amplitude noise in the laser. One scheme is proposed to suppress this kind of instabilities by inserting a highly nonlinear photonic crystal fiber in the ring cavity. The results show that the nonli
