Abstract
A tunable swept multi-laser system comprising a first laser source, a second laser source, a first wavelength blocking component, and a second wavelength blocking component. The first laser source has a first wavelength working range and the second laser source has a second wavelength working range. The first wavelength working range begins at a first start wavelength and ends at a first end wavelength. The second wavelength working range begins at a second start wavelength, ends at a second end wavelength, and overlaps with the first wavelength working range. The first wavelength blocking component has a first wavelength blocking range including the first end wavelength. The second wavelength blocking component has a second wavelength blocking range including the second start wavelength. The first wavelength blocking component is optically coupled with the first laser source and the second wavelength blocking component is optically coupled with the second laser source.
