Abstract:
1. A mode locked waveguide laser system, comprising: a mode locked waveguide laser comprising a laser cavity having a waveguide; an intra-cavity beam emitted from said waveguide; a dispersion control unit (DCU) disposed in said cavity and in an optical path of said intra-cavity beam, wherein said laser cavity is configured in such a way that said intra-cavity beam is redirected to said waveguide after traversing at least said DCU, wherein said DCU imparts: with a single angular dispersion inducing optical element, group-velocity dispersion (GVD) to said intra-cavity beam during propagation in said cavity, and a spatial chirp to said redirected beam, wherein said DCU is capable of producing net GVD in a range from a positive value to a negative value.
