  • Semiconductor laser module
    Patent number: 8477814
    Abstract: A semiconductor laser module is disclosed, comprising a module carrier (20) having a mounting area (21), a pump device (1) arranged on the mounting area (21), a surface emitting semiconductor laser (40) arranged on the mounting area (21), and a frequency conversion device (6) arranged on the mounting area (21), wherein the mounting area (21) of the module carrier (20) has an area content of at most 100 mm2.
    Type: Grant
    Filed: February 13, 2009
    Date of Patent: July 2, 2013
    Assignee: OSRAM Opto Semiconductors GmbH

  • Method for producing a semiconductor laser, and semiconductor laser
    Patent number: 7995633
    Abstract: A method for producing a multiplicity of semiconductor lasers (100) comprising the steps of providing a carrier wafer (30), producing an assembly (70) by applying a multiplicity of semiconductor laser chips (4) to a top side (31) of the carrier wafer (30), and singulating the assembly (70) to form a multiplicity of semiconductor lasers (100). Each semiconductor laser (100) comprises a mounting block (3) and at least one semiconductor laser chip (4). Each mounting block (3) has a mounting area (13) which runs substantially perpendicular to a top side (12) of the mounting block (3), on which top side the semiconductor laser chip (4) is arranged. The mounting area (13) is produced during the singulation of the assembly.

  • Surface emitting laser with an integrated absorber
    Patent number: 7729393
    Abstract: A surface emitting laser (SEL) with an integrated absorber. A lower mirror and an output coupler define a laser cavity of the SEL. A monolithic gain structure positioned in the laser cavity includes a gain region and an absorber, wherein a saturation fluence of the absorber is less than a saturation fluence of the gain region.
