Abstract: A seed laser is configured to emit seed laser light. A plurality of optical amplifiers is configured to generate amplified laser light by amplifying the seed laser light. Each of the optical amplifiers is configured to separately direct its respective amplified laser light to a medium without being optically combined within the laser assembly with any of the other amplified laser light emitted by other optical amplifiers in the plurality of optical amplifiers.

Abstract: A dentition cleaning device and system is disclosed for cleaning teeth, gums and dentures. The dentition cleaning device utilizes squeegees that protrude from a cleaning head to provide efficient contact of dentition surfaces during cleaning. The dentition cleaning device is particularly useful for cleaning teeth because the squeegee contact surfaces and remove residues, such as plaque, without causing significant abrasion to surrounding gum tissue which can lead to gum recession. The dentition cleaning device can be configured with bristle sections or with squeegees that are configured to retain water in squeegee channels. The dentition cleaning device is adaptable to water assisted tooth cleaning system and motorized electric teeth cleaning systems. The dentition cleaning device is also particularly useful to be used in conjunction with a low viscosity tooth cleaner that is capable of being delivered through a conventional pump dispenser.

Abstract: A device, system and method is disclosed for removing residues from surfaces and for applying materials to surfaces. The device system and method of the instant invention utilize a squeegee configuration with a first continuous squeegee edge. Preferably, the first continues squeegee edge protrudes from a squeegee support element with squeegee walls that extend in all directions of a wiping plane. Within the boundary formed by the first continuous squeegee edge there are preferably additional cleaning elements such as bristles, sponges and/or additional squeegees. According to a preferred embodiment of the invention, a second squeegee edge protrudes from the inner squeegee region of the first continuous squeegee edge to form a squeegee compartment. Cleaning solutions and other materials are applied to surfaces by placing the solutions or materials into the squeegee compartment and wiping the surface with the squeegee edges.
