A selectable multiwavelength laser

James Austin Piper (Inventor), Helen Margaret Pask (Inventor)

    Research output: Patent


    A laser system capable of selecting between at least two different wavelengths of output laser light. The system (100) comprises a resonator cavity (105) comprising at least two reflectors (110, 115), and a laser material (125) located in the cavity. A pump source (120) is located outside of the cavity for pumping the laser material (125) with a pump beam to generate a cavity laser beam. A Raman-active medium (135) is also located in the resonator cavity (105) for shifting the wavelength of the cavity laser beam such that at least two different frequencies are generated. A frequency selector is provided for selecting a single frequency of output laser light by either deselecting all but one of the at least two different frequencies or by selecting one of the at least two different frequencies, and an output coupler is used for outputting the single wavelength of output laser light.
