Abstract

The invention discloses a light parameter oscillation-based light frequency comb generator. The light oscillation-based light frequency comb generator comprises a pumping light source light path, a thulium-doped fiber amplification light path and a light frequency comb generation light path, wherein the pumping light source light path, the thulium-doped fiber amplification light path and the lightfrequency comb generation light path are sequentially connected.

Description

technical field [0001] The invention belongs to the technical field of laser light sources, and in particular relates to an optical frequency comb generator based on optical parametric oscillation. Background technique [0002] Optical parametric oscillation is a coherent light source with tunable wavelength. In an optical resonant cavity, the optical parameter oscillates under certain conditions. The use of optical parametric oscillation can convert a laser frequency into coherent output of signal and idle frequency, and it can be tuned in a wide frequency range, which is one of the important means of tunable laser generation. Optical parametric oscillation is currently the only way to generate laser light with a wide range of continuously tunable wavelengths (wavelengths from infrared to visible light and even ultraviolet light). An optical parametric oscillator (OPO) is a wide-tunable coherent light source, which overcomes the limitations of the output wavelength of sol...
