An optical parametric oscillator enables rapid and precise wavelength tuning using grating-order multiplexing, highlighting advancements in fiber optic technology.
We present a gain-switched diode-based fiber-feedback optical parametric oscillator featuring an intracavity echelle grating stretcher. Grating-order multiplexing provides access to multiple highly dispersive tuning ranges. This design enables broadband, extremely rapid, precisely reproducible wavelength tuning.
