Optical frequency synthesizer combines a femtosecond mode-locked Er-doped fiber laser with 4 fiber-coupled laser outputs, a fiber amplifier with supercontinuum generator and an f-2f interferometer. Fully PM fiber scheme ensures uninterrupted operation. A separate control rack may be individually configured for each case, containing control and power supply units, phase offset tuning units, data collection and visualization units along with many other possible options.

The system may also be equipped with: a fiber amplifier for 1560 nm, SHG unit with 780 nm output, supercontinuum generator for 1000-2200 nm, supercontinuum generator for 520-1000 nm, difference frequency generator (DFG).
