摘要： A multi-axial mode frequency conversion system includes two resonators. At least two resonator mirrors define a first resonator cavity. A gain medium is positioned in the first resonator cavity. A pump source supplies energy to the gain medium. The first resonator cavity produces a first beam with a plurality of axial modes that are incident on a doubling crystal in the first resonator and produce a frequency doubled output beam. The first resonator cavity provides a sufficient number of axial modes to oscillate so that the doubled output beam has a noise of less than 3% RMS. At least two resonator mirrors define a second resonator cavity coupled to the output beam from the first resonator cavity. The second resonator is configured to provide resonant enhancement of at least a portion of the plurality of axial modes. A non-linear optical material is positioned in the second resonator and configured to produce a harmonic output beam.

摘要： The ellipticity of a thermal lens is controlled in a diode-pumped anisotropic crystal, such as Nd:YVO4. The crystal has two opposing optical end faces through which a pump beam and an output beam pass. The crystal also has opposing "c" axis crystal faces normal to a "c" axis of the crystal, and opposing "a" axis crystal faces that are normal to an "a" axis of the crystal. A mount supports the crystal and serves as a heat sink. A path is created to conduct heat from the crystal through the "c" faces, while the "a" faces are thermally isolated from heat conduction. The thermal lens ellipticity is controlled in order to produce a round, diffraction limited gaussian beam suitable for applications that require a high power, good quality beam from a simple, reliable laser source.

摘要： A diode pumped, multiaxial mode, intracavity frequency doubled laser resonator has high amplitude stability, meaning that the percent root mean square noise (% RMS) of the doubled output beam power is low. A diode pump source supplies a pump beam to a laser crystal positioned in a resonator cavity and produces a multiaxial mode infrared beam that is incident on a doubling crystal, also positioned in the resonator. A frequency doubled output beam is produced that has an RMS of less than 3%. The laser is highly efficient, provides high output power and its output beam is of high spatial quality.

摘要： An optically pumped laser has a gain medium positioned inside of an optical resonator cavity and disposed about a resonator optical axis. An optical pumping source is positioned outside of the optical resonator cavity. A reflective coupler with a coupler body, and an interior volume passing therethrough is positioned proximal to the optical pumping source. Light from the pumping source passes into an entrance aperture of the reflective coupler to an exit aperture of the reflective coupler positioned distal to the optical pumping source. The interior volume of the reflective coupler is bounded by a reflective surface, an entrance aperture and the exit aperture, and is substantially transparent to radiation from the optical pumping source. The reflective surface has a high reflectivity matched to radiation from the optical pumping source. The reflective coupler directs radiation from the optical pumping source into the optical resonator cavity and gain medium, conditioning the numerical aperture and spatial intensity distribution across the exit aperture.
