Description

The FC800 is a Ti:Sapphire based Optical Frequency Comb with a mode spacing of 1 GHz. Its oscillator is the Laser Quantum taccor turn-key femtosecond laser. Menlo Systems’ robust and mature one-arm f-2f interferometer technology together with our optimized control loops and our established software packages for automation and data evaluation enables us to combine Ti:Sapphire low-noise performance and high repetition rate in a frequency comb system designed for 24/7 operation. This Optical Frequency Comb is as simple as our well-known FC1500 fiber-based frequency comb systems being workhorses in labs all over the world.
