The FC8004 is an optical frequency synthesizer, manufactured by Menlo Systems. This product can generate and measure optical frequency having unusual accuracy and stability. It is compliant to mode-locked Ti: Sapphire ocsillator. It also produces 500.000 precise laser lines that has a 200 MHz equal spacing.
To generate an octave spanning spectrum, the output from the laser is spectrally broadened in a photonic fiber. Between the 1,064-nm and 532-nm components, the offset frequency is generated.
The device is operated with 10-14 accuracy rates, 5 x10-13 in 1 sec., including 630-850 nm output port 1 and 532, 1,064-nm output port 2. It is equipped with an automated comb control and a data acquisition software system.
