ABSTRACT: In this paper, new configuration is proposed, investigated and analyzed.
Fiber laser and fiber amplifier are merged in one configuration which called
Erbium Doped Fiber Laser and Amplifier (EDFLA) or integrating EDFL and EDFA in
one design. The configuration has three main outputs; one for laser, second for
amplifier and the third it can be used for on/off output. A surprising phenomenon
was remarked during the operation of this configuration. The amplification is
abolished during the lasing state and appeared again if the lasing is stopped
or the switch is off. The difference between outputs with the lasing and
without lasing has 30 dB EDFA gain value; it is a good sign that this optical
configuration can be used as an on/off integrated optical device for fiber laser.
