Patent number: 5099488Abstract: A laser array submount structure for assembly into a two-dimensional stacked array with precise separation between laser diodes of adjacent submounts. The submount includes a deformable metal layer, such as a soft solder, on one major surface of a laser array support plate. A spacer element having spaced apart ridges is disposed on the opposite major surface. A laser diode array is mounted on a front edge of the support plate.

Patent number: 4818062Abstract: An optical system producing bright light output for optical pumping, communications, illumination and the like in which one or more fiberoptic waveguides receive light from one or more diode lasers or diode laser bars and transmit the light to an output end where it is focused or collimated into a bright light image. The input end of the fiberoptic waveguides may be squashed into an elongated cross section so as to guide light emitted from an elongated light source such as a diode laser bar. The waveguides are preferably arranged at the output end into a tightly packed bundle where a lens or other optical means focuses or collimates the light. For diode laser bars much wider than 100 microns, a plurality of waveguides may be arranged in a line to receive the light, and then stacked at the output in a less elongated configuration. In this manner, light from many diode lasers or laser bars may be coupled through the bundle into the end of solid state laser medium.Type: GrantFiled: March 29, 1988Date of Patent: April 4, 1989Assignee: Spectra Diode Laboratories, Inc.Inventors: Donald R.

Patent number: 4688884Abstract: A fiberoptic coupling system comprising a phased array semiconductor laser and a squashed multimode light transmitting fiber. The squashed input end has an oblong, preferably elliptical, or polygonal cross-section with major and minor core widths. The major width decreases toward an output end which preferably has a circular cross-section. The minor width may increase toward the output end or remain constant. This increase and decrease correspond to the characteristic laser light beam widths and divergences in planes parallel and perpendicular to an active region of the laser such that the fiber core widths are at least as large as the laser light beam widths and the fiber has input numerical apertures that cause the beam to be coupled at the divergences. This system has a light coupling efficiency of at least 70 percent.Type: GrantFiled: November 12, 1985Date of Patent: August 25, 1987Assignee: Spectra Diode Laboratories, Inc.Inventors: Donald R.
