FC1000
(Optical Frequency Comb)
Optical Frequency Comb Based on PM Ytterbium Fiber Oscillator
The FC1000 Optical Frequency Combs a compact and flexible fiber-based frequency comb system for direct measurement of absolute optical frequencies. The laser operation relies on the figure 9® mode locking technology, which ensures excellent stability and low-noise operation. The femtosecond laser is ready to use at the press of a single button, and automatic phase lock loops ensure easy stabilization to either a RF or an optical reference. Due to the mature system design including several motorized actuators, our customers report long-term operation where the comb is phase locked over weeks. With a wide range of optional addons, we tailor individual systems to customer specific requirements. With the optional ASTRO Extension Package the system offers high mode spacing. Spectral broadening and flattening stages generate the output in the user-defined, visible wavelength range (e.g. 450-700 nm)
Complete Solutions:
The optical frequency comb is a complete system including mode locked Yb-doped fiber laser with PM output, that is spectrally broadened to generate the octave-spanning spectrum, and an f:2f interferometer. The The turn-key, fully hands-off optical setup offers compactness in an extremely robust design and features 24/7 operation with remote access to measured data. A separate rack cabinet houses control units, phase-locked-loops, data acquisition, and displays.
