    Abstract: An optical parametric oscillator comprising: an optical cavity; a semiconductor gain- medium (14) located within the optical cavity, such that together they form a semiconductor laser, and a nonlinear material (24) located within the cavity such that the nonlinear material continuously generates down- converted idler- and signal-waves in response to a pump-wave continuously generated by the semiconductor gain-medium, wherein the pump wave is resonant within the optical cavity and one or other but not both of the down-converted waves is resonant within the pump wave cavity or a further optical cavity. Brewster plates (40) ensure singly resonant OPO and a birefringent filter (30) is used for frequency setting. Coupled cavities alllow for setting the photon lifetime in the cavity that relaxation oscillations are prevented.

    Abstract: A method of optimising parametric gain in a nonlinear optical crystal that in response to application of a pump beam generates through a parametric generation process signal and idler beams, wherein the signal beam is non-collinear with the pump beam and the signal beam is subject to absorption due to the nonlinear material, the method involving shaping the pump beam to have an elliptical cross section, wherein the method further involves determining the width w of the pump beam depending on the absorption co- efficient of the optical crystal.

    Abstract: A frequency comb generator (10) comprising a non-linear material (16), such as a non-linear crystal, that produces two or more down-converted waves when optically stimulated using an optical pump (14). The generator (10) has two optical cavities (18, 28), the first (18) being a pump wave cavity in which radiation from the pump is resonant, the second being a down converted wave cavity (28) in which one or more of the down-converted waves is resonant. The non-linear material (16) is included in the pump cavity. Included in the down-converted cavity (28) is a phase modulator (12).
