Provided are a laser device and a method of transforming laser spectrum, which provide a laser frequency stabilization and significant narrowing a laser spectrum. A laser device includes at least one multiple longitudinal mode laser (L) for generating a laser light having a spectrum of multiple longitudinal modes; at least one high quality factor (high-Q) microresonator (M) optically feedback coupled to the at least one multiple longitudinal mode laser (L); and a tuner (TU) for tuning the spectrum of multiple longitudinal modes of the laser light. The laser device is configured to output an output laser light having an output spectrum with at least one dominant longitudinal laser mode each at a reduced linewidth of the dominant longitudinal laser mode. The laser device allows increasing an emission power of a narrow linewidth lasing without an additional amplification while keeping a compact size of a device with a limited number of optical elements.

Provided is an optical source apparatus that may generate two different optical frequency combs. The optical source apparatus includes an optical resonator and a continuous wave laser emitting laser light having a spectrum component corresponding to a resonance frequency of the optical resonator, and the optical resonator is configured to generate a first frequency comb and a second frequency comb having different modes by interacting with the laser light emitted by the continuous wave laser.
