Abstract
A laser device including a first cavity forming a Mamyshev oscillator, comprising a bandpass first filter at the first wavelength, and a second filter that also transmits the wavelength but that is reflective at a second wavelength, a second cavity, containing the first cavity, for forming a continuous-wave laser beam at the first wavelength and/or at a third wavelength neighbouring the first wavelength, the separation between the first and third wavelengths being smaller than the spectral width of the first filter and of the second filter, and means for allowing or interrupting a continuous-wave oscillation at the first wavelength or at said neighbouring wavelength, in the second cavity.
