EAR SF Series: 1-100W C & L Band Single Frequency Erbium Fiber Amplifier Laser

The EAR-SF Series is a line of universal broadband, high power, single frequency, single mode fiber amplifiers covering the spectral range from 1540 to 1600nm. The series includes 1 to 100 W versions. These user friendly devices are designed to serve laboratory or OEM maintenance free applications over a wide range of ambient conditions.

Typical bandwidth of the amplifier is 10-25nm (depending on output power) which allows for tunability of input signal for exact wavelength matching.  Input power range can vary from microwatts to 100s of milliWatts.  EAR-SF Series amplifiers do not need water cooling or replacement parts. They require only a 110/220V AC power source to provide amplification for your low power signal.

EAR-SF Series is optimized for single frequency linewidth amplification of CW or pulsed input signals. They can be used for variety of applications including coherent or spectral beam combining, detection system, atmospheric measurements, free-space communications, and other applications.
