Based on a refined homodyne technology, the OE4000 and OE 4001 systems from OEwaves the most precise determination of the laser properties of narrow-band single frequency cw lasers. Line width, phase noise and intensity noise can be measured with high precision over a selectable offset range. There OEwaves even produces extremely narrow-band and low-noise SF lasers which are used for satellite communication or in the demanding telecommunications sector, the optical test devices have been optimized accordingly.
The large wavelength range of 500 nm – 2100 nm for which the devices are used should also be emphasized.
