Erbium-Doped Pulse Amplifier, 36 dBm (EDPA-1550-R)

Data Sheet

The Optilab EDPA-1550-R Erbium-Doped Pulse Amplifier is designed to amplify optical pulses up to 3 kWpeak power.

Product Overview

The Optilab EDPA-1550-R Erbium-Doped Pulse Amplifier is designed to amplify optical pulses up to 3 kWpeak power. The EDPA-1550-R has triple stages of amplification with optical gain up to 50 dB. Based on multi-mode pumping Er/Yb double clad fiber technology, EDPA-1550-R is designed to produce high outputpower while minimize the back reflection. Customized optical filters are incorporated to reduce Amplified Spontaneous Emission (ASE) noise. The EDPA-1550-R has an output power level of up to +36 dBm at CW mode. The fiber output port can be lensed fiber, FC/APC or collimator. It is equipped with an LCD display screen and front panel knob for easy user interface control or remote control via USB. The Optilab EDPA- 1550-R can be customized to various pulse applications. Contact Optilab for more information.
