HI-Q® Yellow Laser

Blue laser with ultra-narrow Lorentzian Linewidth and low phase/frequency noise in a compact form factor in the 550 nm range

The HI-Q® laser houses a proprietary driver/controller and the OEwaves laser source which is based on a high quality factor (Q) Whispering Gallery Mode (WGM) optical micro-resonator. The laser is available at a variety of wavelengths around 550 nm.
