Claim 16:
17. A method for producing a substantially mode-hop-free laser system, comprising:
providing one or more semiconductor laser devices; and
forming a folded cavity external to the one or more semiconductor laser devices including:
positioning at least one of the one or more semiconductor laser devices at a fold in the folded cavity;
positioning at least one mirror in the folded cavity to enable sustained propagation of light within the folded cavity; and
positioning at least two polarization elements in the folded external cavity, the at least two polarization elements configured to cause a polarization state of light that impinges in a first direction on each semiconductor laser device that is positioned at a corresponding fold to be orthogonal to a polarization state of light that impinges in a second direction on each semiconductor laser device that is positioned at the corresponding fold.
