Fiber Optic Comb and Microwave Generation System

IMRA America offers a high performance frequency comb for advanced metrology applications, such as optical clocks and comb spectroscopy. The rack-mounted comb integrates easily, especially where a portable system is premium. An all-erbium platform, the frequency comb comes with fiber-coupled outputs and provides ultra-low phase noise, timing jitter, and superior frequency stability. IMRA provides 80MHz/100MHz/200MHz/250MHz repeat frequency fiber optical combs. At the same time, we provide mid-infrared optical combs, microcavity optical combs, and microwave generation systems; as well as optical comb mode-locked oscillators, f2f modules, locking control modules, and amplification and beat frequency modules.

Main features:

· 100MHz/200MHz/250MHz repetition frequency

· Output 530nm-2200nm, expandable to ultraviolet and mid-infrared bands

· Stability 10^-16~10^-19/1s

· High long-term stability (continuous locking for several months without unlocking)

· Compact size and small size: 1/5 of its counterparts

· Automatic locking, local and remote management

· Super cost-effective

· No installation required; can be managed locally and remotely

· Especially suitable for use in harsh environments, such as environments with limited space, handling and large temperature changes.
