Abstract
A method is provided for seeding laser system () for single longitudinal mode oscillation. The method includes coupling laser system () to be seeded for single mode output to a seed laser radiation source (). Next, the frequency capture range () and spacing () of the axial modes () of the cavity () of the laser system () are determined. A seed spectrum () is then generated from the seed laser radiation source () with a bandwidth () corresponding to the axial mode spacing (). The seed spectrum () includes a comb of discrete frequency components () with one or more of the discrete frequency components () being within the frequency capture range () of at least one of the axial modes (). The seed spectrum () is then injected into the cavity () such that at least one of the axial modes () oscillates with the seed radiation.
