New erbium doped fiber laser amplifier

Abstract

A new configuration of laser and amplifier is constructed and investigated. This configuration is called erbium doped fiber laser amplifier (EDFLA) where both the laser and amplifier are included in one configuration. The new configuration is utilized as optical amplifier, laser source, and ON/OFF optical tool. A surprising characteristic of the configuration is remarked when the lasing is ON the absorption and amplification are abolished.
