    Research output: Patent


    A tunable lasing device including a vertical external cavity surface emitting laser, adapted to generate a fundamental laser beam in response to pumping from a pump source, said fundamental laser beam having a fundamental wavelength and a fundamental linewidth; a fundamental resonator cavity adapted to resonate the fundamental beam therein; a first optical element located within the fundamental resonator cavity for control of the fundamental linewidth of the fundamental beam; a Raman resonator located at least partially in said fundamental resonator adapted to receive the fundamental beam and comprising therein, a solid state Raman active medium located therein for generating at least a first Stokes beam from the fundamental beam wherein said Raman resonator cavity is adapted to resonate said Stokes beam therein and further adapted to emit an output beam; and further comprising a nonlinear medium located within the Raman resonator cavity for nonlinear frequency conversion of at least one of the beams present in the fundamental or the Raman resonator cavity; said tunable lasing device further comprising an output coupler adapted to emit an output beam, said output beam comprising at least a portion of said frequency converted beam being derived from at least one of the resonating beams in said fundamental or said Raman resonator cavities.
