Feature Comparison: SF PM Amplifiers

Feature Comparison Matrix

The second generation of Nufern's narrow linewidth PM amplifiers offers a number of improvements and new capabilities over the previous generation. Some of the key differences are described below.

From here, you can return to the 1.0 µm amplifiers or the 1.5 µm amplifiers.

  Gen I Gen II New Benefits
Output Power 2W, 5W, 10W  
Input Power > 50 mW > 1 mW or > 50 mW Compatible with more low-cost seed sources.
Input Power Loss Protection Best in class Improved Lowest risk of catastrophic failure.
Output Power Monitor Not avail. Integrated Enables low-cost closed loop control.
Output Wavelength 1040–1090 nm 1040–1090 nm or
1540–1570 nm		 New broader wavelength range.
Output Isolation None, Fiber→Fiber (internal), or
Fiber→Free Space (external)		 Same application flexibility.
Back Reflection Protection Best in class Improved Lowest risk of catastrophic failure.
Diode Drivers Customer supplied Integrated Reduces cost and complexity of lab.
SBS at Rated Power SBS limited Reduced SBS Lowest noise measurements possible.
PC Control Custom only Optional via USB Easier to set up and use.
E-stop & Key Switch Custom only Optional Easier, safer installations.
Remote Interlock Custom only Standard Easier, safer installations.
