Product Info
Main Specification
Adopting optical communication diode laser packaging technology, Precilasers developed FECL in a tiny butterfly-package. Meanwhile with the low-noise and high modulation-bandwidth driver, Precilasers' FECL shows ultra-narrow linewidth (< 10 kHz), ultra-low intensity noise (<-150 dBc/Hz @100 kHz) , and large modulation bandwidth(> 5MHz).
FECL is widely used in areas like transportable atomic clock, and gravity meter, optical lattice, radar, coherent optical communication, high-precision optical sensing, quantum metrology.
