YAR-LP-SF, 1-100 W

Single Frequency Ytterbium Amplifiers

The YAR-LP-SF Series is a line of linearly polarized (LP) single frequency (SF) single-mode fiber amplifiers covering the spectral range from 1030-1070 nm. Typical bandwidth of the amplifier is 10-20 nm (depending on output power) which allows tunability of the input signal for exact wavelength matching. The series includes 1-100 W versions. These user friendly and highly efficient 19” rack mounted devices are designed for maintenance-free applications over a temperature range of 10°C to 35°C. The YAR-LP-SF Series is optimized for linearly polarized single frequency input signals and can be used for a variety of applications including coherent beam combining, detection systems, sensing and other applications.


YAR-LP-SF Series amplifiers provide amplification of linearly polarized, single frequency input signals.

The standard amplifier has a 25 dB input optical isolation and <-60 dB residual pump power at the input and output ports. The typical extinction ratio is ~20-23 dB.

The YAR-LP-SF Series amplifier provides control over output power via a front panel touch screen display, RS-232, or Ethernet. All controlled and read parameters can be found in a User Guide.


IPG’s YAR-LP-SF Series amplifiers do not need water-cooling or replacement parts and requires only a 110/220V AC power source to provide amplification for your low power signal.

All YAR-LP-SF Series amplifiers wavelength stabilized. Estimated diode lifetime for these diodes is >100,000 hours at 25°C.
