Abstract: Devices, systems, and methods for generating high power flattop laser beams are disclosed. Schematics and arrangements of diodes, fast axis and slow axis cylindrical lens arrays, collimation lenses, and other optics are described and disclosed. Also disclosed are methods of generating flattop beams for myriad applications.

Abstract: A high power uniform light beam is generated on an oblique plane by one or more diode lasers and 2 or more light pipes. The light pipes may be trapezoidal so that the illuminated area is substantially square. The light pipes may be elliptical so that the illuminated area is substantially circular.

Abstract: The present invention provides a way to use anisotropic laser gain media to make a laser that can lase in two longitudinal modes at different wavelengths with orthogonal polarizations. The two longitudinal mode (LM) laser output can be separated to generate two single LM outputs. This type of lasers can also be used to generate low noise continuous wave (CW) harmonics through intracavity harmonic generation.

Abstract: Devices, systems, and methods for generating ultraviolet lasers are disclosed. Schematics and arrangements of a combination structure implementation that often uses an intra-cavity second harmonic generation (SHG) element and a UV extractor often with a birefringent crystal (BC) to extract the UV light are described and disclosed. A Nonlinear crystal (NLC) may serve as the SHG element and volume Bragg gating (VBG) may be included to control pump light characteristics.

Abstract: This invention proposes to use a specially designed layered nonlinear optic (LNO) for intracavity harmonic generation. The LNO generates the harmonic and guides the generated harmonic beam to a different path from the fundamental beam path with total internal reflection, a phenomenon that all lights are reflected when lights in one (“internal”) optic strike sufficiently obliquely against the interface with a second (“external”) optic, in which the refractive index is lower than that in the internal optic. No coating is necessary for the harmonic inside the fundamental beam laser cavity. The generated harmonic beam does not travel through any surface inside the fundamental beam cavity, either. Hence this invention improves the reliability of intracavity harmonic generation laser especially if the harmonic is in the UV range.

Abstract: Arrangements of multi-core fibers, devices, and systems with two or more cores, defined by a core separation of less than a cross-sectional diameter of a discrete single core unmodified fiber, and methods of using are provided and/or described herein. Arrangements of fibers, devices, and systems with three or more cores, defined by a core separation of less than a cross-sectional diameter of a discrete single core fiber, and methods of using are provided and/or described herein. Also, disclosed are methods of manufacturing and joining two or more single rectangular (or square core) fibers to form two or more lines of illumination for myriad applications.
