Femtosecond optical frequency combs have led to a revolution in our ability to measure the frequency of light. This approach vastly enhances and simplifies dimensional metrology and enables new directions in physics. The FC1000-250 measures optical frequencies with unprecedented accuracy (up to 14 digits) and stability. It is based on a mode-locked Ytterbium-doped oscillator and provides 500,000 precise laser lines with equal spacing of 250 MHz. The output is spectrally broadened to generate an octave-spanning spectrum. The offset frequency beat is generated in a stable, rigid f:2f interferometer. The system is designed and engineered for 24/7 operation. 
Consecutive pulses and the corresponding spectrum of the pulse train emitted by a mode locked laser. The carrier wave (shown in blue) shifts by Δϕ after each round trip with respect to the pulse envelope (shown in red). This continuous shift results in a frequency offset f0=Δϕ/Τ of the comb. Stabilization of the offset frequency and the pulse to pulse phase slippage by frequency doubling the infrared part of the comb and observation of the beat with the blue part. | Please note that the FC1000-250 is available directly from Menlo Systems, Inc. within the United States and from Menlo Systems GmbH outside the United States. | United States
