Abstract: A mode locking semiconductor disk laser (SDL) comprising a resonator terminated by first and second mirrors and folded by a third mirror is presented. The third mirror includes a semiconductor disk laser (SDL) suitable for generating a resonator field having a predetermined central wavelength ?0, while the second mirror includes an intensity saturable mirror suitable for mode locking the resonator field at the predetermined wavelength. The central wavelength of the reflectivity profile of the first and or second mirrors is shifted to a wavelength shorter than the central wavelength ?0 to suppress gain at wavelengths longer than the central wavelength ?0. By mismatching the reflectivity profile of the first and or second mirrors to that of the desired output wavelength provides a stable mode locked laser with significantly reduced noise.

Abstract: An automated method for managing the repair, remanufacture, or refurbishment of electronic products, such as smart cellular phones and tablet computers, based on expected economic returns, beginning with the initial “triage” assessment, and continuing with established check points to validate continuation of the repair process. Parameters used to make this determination include the anticipated market value of the product, projected material and labor costs at any point in the process, and the expected probability of a successful repair completion. Companies engaged in this business usually have a method of projecting the expected cost of repairing an electronic product. However, if the actual repair cost exceeds the projection, this is often not realized until after the completion of the repair or refurbishment, resulting in an economic loss. This automated method provides economically intelligent process routing to prevent that occurrence.

Abstract: Described is a device for inducing crystal nucleation in a crystallizer. The device comprises a vessel for fluid and a surface abrader, wherein the surface abrader is configured to abrade a surface within the vessel to induce crystal nucleation. The friction of the abrader against the surface within the vessel creates nano-sized particulates which induce crystal nucleation. Crystal growth can then take place in the crystallizer. Also described is a crystallization apparatus comprising the device and a crystallization process using the device or similar. The device is significantly cheaper and more reliable than known ultrasound devices and facilitates the separation of crystal nucleation and crystal growth. The device also enables the avoidance of the use of seeding as a source of secondary nucleation.
