The FC1000-250 from Menlo Systems is an Optical Frequency Comb that operates at a wavelength of 1040 nm. It delivers an average output power above 5 mW (from each laser port) and has a spectral range of greater than 20 nm. This linearly polarized OFC has a comb spacing of 250 MHz and tuning range of over 2 MHz. It has a Carrier-Envelope Offset frequency tuning range above 250 MHz and wavelength accuracy of ±10 nm.
The FC1000-250 has an accuracy of up to 1 x 10-14 (in 1000 s) and a stability of less than 5 x 10-13 (in 1 s). It has a fully automated turnkey metrology system that includes data evaluation software designed for continuous operation and can combine multiple extensions in a system. This OFC uses polarization-maintaining figure 9® mode-locking technology with motorized actuators and has an optional ASTRO Extension Package for high mode spacing.
The FC1000-250 includes a mode-locked Yb-doped fiber laser with two fiber-coupled laser outputs and an f:2f interferometer. It requires an AC supply voltage of 100/115/230 V and consumes below 500 W of power. This OFC is available in a compact module that measures 706 mm x 716 mm (optical unit) & 600 mm x 800 mm (control electronics) and is ideal for high-precision CW laser stabilization, Fourier Transform Infrared (FTIR) spectroscopy, calibration of lasers, high-resolution spectroscopy, and low-noise microwave generation applications.
