摘要： An optical antenna collects, modifies and emits energy at light wavelengths. Linear conductors sized to correspond to the light wavelengths are used. Nonlinear junctions of small dimension are used to rectify an alternating waveform induced upon the conductors by the lightwave electromagnetic energy. The optical antenna and junctions are effective to produce harmonic energy at light wavelengths. The linear conductors may be comprised of carbon nanotubes that are attached to a substrate material, which may then be connected to an electrical port.

摘要： A third-harmonic crystal has a Brewster-cut dispersive output surface for separating the p-polarized fundamental and third-harmonic beams without introducing losses into the beams. The output surface of the third-harmonic crystal is optically uncoated, and thus insensitive to potential ultraviolet (UV)-induced damage. Frequency doubling and tripling lithium triborate (LBO) crystals are used with a Brewster-cut Nd-YAG active medium in a resonant cavity to generate UV light at 355 nm from infrared (IR) light at 1064 nm. Except for the tripling crystal output surface, the doubling and tripling crystal optical surfaces are normal-cut and anti-reflection (AR) coated.

摘要： In a laser having a frequency conversion element or a non-linear optical element such as a second-harmonic generation (SHG) element arranged on an optical axis of a laser light and outputting a frequency-converted laser light, laser incident and emitting faces of the SHG element have such convex form as cylindrical lenses with a common center axis of curvature thereof and orthogonal to the optical axis of the laser light. The SHG element is rotatable about the common center axis of curvature so that an optimum control of phase matching angle is possible. Since the common center axis of curvature of the laser incident and emitting faces of the SHG element is coincident with the rotational axis thereof, an optical axis of a fundamental wave of the laser light source is not deviated when the SHG element is rotated and thus reduction of fundamental wave laser output can be restricted. Further, a control mechanism for always maintaining wavelength conversion efficiency of the SHG element at maximum may be added, in which changes of a second-harmonic wave output light, caused by minute variation of rotation angle given to the SHG element, is detected to automatically control the phase matching angle.

摘要： An extra cavity harmonic generator system may produce a round, non-astigmatic third harmonic output beam from a nominally round, non-astigmatic, diffraction limited input fundamental beam. The system may include a second harmonic generation crystal. An input fundamental beam size is expanded in a non-walkoff direction for the SHG crystal at the SHG crystal input face. A higher harmonic generation crystal has an output face oriented at an oblique angle of incidence in a non-walkoff direction for the HHG crystal such that an output higher harmonic beam size is contracted in this direction. Expansion of the input fundamental beam at the SHG crystal input face exceeds reduction of third harmonic beam at the HHG crystal output face.

摘要： An optical output coupler includes an uncoated plano-concave lens having a planar side and a concave side. An optical axis of the plano-concave lens is tilted at or near a Brewster angle relative to a beam axis. A first optical element is configured to focus a beam of radiation emerging from the planar side of the plano-concave lens along a first axis that is perpendicular to the beam axis. The first optical element is disposed between the planar side of the plano-concave lens and a second optical element. The second optical element is configured to focus a beam of radiation emerging from the planar side of the plano-concave lens along a second axis that is perpendicular to the beam axis, wherein the second axis is different from the first axis.

摘要： A cascaded harmonic generator, for cascaded optical harmonic generation from an optical beam provided by a laser source, may include a second harmonic generator to generate a second harmonic optical beam based on a residual beam associated with the optical beam. The cascaded harmonic generator may include a third harmonic generator to generate a third harmonic optical beam based on the second harmonic optical beam and the optical beam. The third harmonic generator may be positioned in an optical path upstream from the second harmonic generator. A harmonic generator delay time, associated with the optical path, may be approximately equal to, or may be an approximate integer multiple of, a laser source round-trip time.
