    Research output: Patent


    The invention provides a wavelength converter (10) for generating at least one wavelength of output laser light (40) from'a pump laser beam (35). The wavelength converter comprises a resonator cavity (15) comprising at least a first reflector (20) and a second reflector (25), and a Raman-active medium (30) located in the resonator cavity (15) and an output coupler (25). , The Raman-active medium (30) is capable of shifting the wavelength of the pump laser beam (35 to generate Raman-shifted laser light, and the first and second reflectors (20, 25) are adapted and disposed so as to reflect said Raman-shifted laser light having at least one selected wavelength a plurality of times through said Raman medium (30) so as to provide medium to high gain Raman-shifted laser light (40) having at least one selected wavelength.
