Publication number: 20170229835Abstract: A laser amplifier includes a broadband laser gain medium having a first lateral face spaced from an opposing second lateral face at a wedge angle with respect to the first lateral face. At least the first lateral face receives a pump beam and one of the first and second lateral faces receives a seed beam.

Patent number: 9229307Abstract: An apparatus comprising a visible light source(s), multimode optical fiber(s), light coupler(s), an optional spatial light modulator(s), and an optional projection lens(es). The light source has a 1/e half-width emission bandwidth. The light coupler couples the light source to the multimode optical fiber(s) such that objective speckle contrast is reduced. The multimode optical fiber(s) may pass light from the coupler to an optional spatial light modulator. The spatial light modulator may modulate the light to form an image. The projection lens may transfer light onto an image plane or to illuminate objects. The objective speckle contrast at the end of the multimode fiber in combination with the projection lens diameter (if employed) and wavelength diversity may result in viewed images at the viewer's eye, or other detector, exhibiting speckle contrast that may be 1% or less.Type: GrantFiled: February 24, 2015Date of Patent: January 5, 2016Assignee: JGM Associated, Inc.Inventors: Jeffrey G Manni, Joseph W Goodman
