3 Hz Linewidth Laser Module

The OEwaves OE4040 Lasers offer ultra-narrow Lorentzian linewidth and low phase/frequency noise in a compact form factor. The unique technology of the OEwaves HI-Q ® laser leverages proprietary self- injection locking of a laser diode via resonant optical feedback from a high quality factor (Q) Whispering Gallery Mode (WGM) micro-resonator to achieve unmatched low noise performance.
