Fixed External Cavity Diode Laser
Fixed External Cavity Diode Laser
Compared with the traditional external cavity diode laser, FECL (fixed external cavity diode laser) has no movable elements in the structure. Thus it is able to work under heavy environment temperature variation and vibration, still free of mode-hop.

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.
