Patent number: 10122150Abstract: A surface-emitting semiconductor laser system contains at least one MQW unit of at least three constituent QWs, axially separated from one another substantially non-equidistantly. The MQW unit is located within the axial extent covered, in operation of the laser, by a half-cycle of the standing wave of the field at a wavelength within the gain spectrum of the gain medium; immediately neighboring nodes of the standing wave are on opposite sides of the MQW unit. So-configured MQW unit can be repeated multiple times and/or complemented with individual QWs disposed outside of the half-cycle of the standing wave with which such MQW unit is associated. The semiconductor laser further includes a pump source configured to input energy in the semiconductor gain medium and a mode-locking element to initiate mode-locking.Type: GrantFiled: November 15, 2017Date of Patent: November 6, 2018Assignee: ARIZONA BOARD OF REGENTS ON BEHALF OF THE UNIVERSITY OF ARIZONAInventors: Isak R. Kilen, Stephan W. Koch, Jerome V. Moloney

Patent number: 8609461Abstract: Various embodiments provide methods for forming a diamond heat spreader and integrating the diamond heat spreader with a heat source without generating voids at the interface. In one embodiment, a semiconductor layer can be epitaxially formed on a diamond substrate having a desirably low surface root mean square (RMS) roughness. The semiconductor epi-layer can be used as an interface layer for bonding the diamond substrate to the heat source to provide efficient heat spreading.Type: GrantFiled: May 11, 2010Date of Patent: December 17, 2013Assignee: STC.UNMInventors: Ganesh Balakrishnan, Jerome V.

Patent number: 6130903Abstract: An MFA-MOPA that includes a semiconductor laser with separate master oscillator and trumpet-flared power amplifier regions. Within the trumpet-flared active gain region of the uniformly-pumped power amplifier of the MFA-MOPA device, the density distribution of carriers and reflections of the laser beam are analyzed to determine the output powers at which filamentation and beam degradation due to reflections occur. The shape of the trumpet-flare is optimized to delay the onset of filamentation and the degradation of the output laser beam due to reflections to higher output powers for the MFA-MOPA device.Type: GrantFiled: February 6, 1998Date of Patent: October 10, 2000Assignee: The Arizona Board of Regents on behalf of the University of ArizonaInventors: Jerome V.
