摘要： A solid state laser medium comprising at least one cooling element, i.e. cooling element, in contact with and alternating in series with at least one gain element. At least one cooling element and at least one gain element are joined at an interface having a center point, wherein the interface is physically modified at the interface such that the heat transfer coefficient at the interface decreases radially from the center point of the interface. The modified interface promotes thermal transfer from the gain element in the axial direction, in such a manner as to reduce thermal distortion affecting optical properties of the laser. Concentric radially disposed barriers to heat flow that hinder heat flow in the radial direction may be added within the gain element to further reduce thermal distortion within the laser medium.

摘要： A laser cavity includes two half shells adapted to be held together forming a sealed, integrated laser structure. The laser cavity is adapted for retaining an excitation source and a lasing medium. At least one coolant passage formed in at least one of the half shells causes liquid to flow transversely over the excitation source and lasing medium. At least one coolant passage formed in at least one of the half shells removes liquid from the laser cavity after the liquid is caused to flow transversely over the excitation source and lasing medium. An inlet formed in at least one of the two half shells can transport liquid into the laser cavity and through the coolant passages. An outlet formed in at least one of the two half shells can remove coolant from the laser cavity after the liquid is caused to flow transversely over the excitation source and lasing medium.

摘要： A diode-pumped solid-state laser oscillator optically pumps a laser medium. The oscillator has at least one pumping light source that emits light in a predetermined wavelength band, and a laser medium that absorbs light in the wavelength band. In the wavelength band, the optical absorption index of the laser medium increases with an increase in wavelength, and the optical radiation energy of the light source decreases with an increase in wavelength. Thus, with respect to wavelength changes, an increase in the optical absorption index is cancelled out by a decrease in the radiation energy, making the stability of the laser output less dependent on the temperature of the optical pumping medium or laser medium.

摘要： A cavity assembly includes a mounting member, an active gain medium, at least one electro-optic component and at least one alignment assembly. The mounting member defines an aperture within which the active gain medium is disposed, and is comprised of a thermally conductive material. The alignment assemblies are disposed relative to the active gain medium, and are configured to receive the electro-optic components such that electro-optic components at least partially align with the active gain medium. The alignment assemblies are rotatably disposed relative to the active gain medium such that relative rotation of the alignment assemblies and the active gain medium alters the alignment of the respective electro-optic components with respect to the active gain medium. The cavity assembly may be mounted within a thermally conductive housing to transfer heat away from the active gain medium.

摘要： A compound planar waveguide comprising multiple confinement structures that provides independent containment of pump and laser radiation. The waveguide may be formed of multiple layers of laser-active and laser-inactive materials to provide step changes in refractive index. The planar waveguide may include a central laserable core layer substantially sandwiched by at least two non-laserable cladding layers to provide an interface between the inner surfaces of the cladding layers and the gain medium core to define a first waveguide by virtue of an index of refraction discontinuity for containing developed laser radiation, and wherein the outer surfaces of the cladding layers define a second waveguide by virtue of an index of refraction discontinuity for containing pump radiation within the waveguide. The second waveguide may be also defined by an interface formed between the cladding layers and additional non-laserable external layers which sandwich the cladding layers. The laser waveguide provides confinement of developed laser radiation which may be independently configured from the waveguide structure that confines the pump radiation. The planar waveguide layers may be also optically bonded together and consist of different optical quality crystals or glass.
