Abstract: Laser diode packages include a rigid thermally conductive base member that includes a base member surface situated to support at least one laser diode assembly, at least one electrode standoff secured to the base member surface that has at least one electrical lead having a first end and a second end with the first end secured to a lead surface of the electrode standoff, and a lid member that includes a lid portion and a plurality of side portions extending from the lid portion and situated to be secured to the base member so as to define sides of the laser diode package, wherein at least one of the side portions includes a lead aperture situated to receive the second end of the secured electrical lead that is insertable through the lead aperture so that the lid member extends over the base member to enclose the laser diode package.

Abstract: Beam compressors include separated surfaces having positive and negative optical powers. A surface spacing is selected so that a collimated beam input to the beam compressor is output as a collimated beam. In some examples, beam compressors are situated to compress a laser beam stack that includes beams associated with a plurality of laser diodes. Beam compression ratios are typically selected so that a compressed beam stack focused into an optical waveguide has a numerical aperture corresponding to the numerical aperture of the optical waveguide.

Abstract: A method of spectrally multiplexing diode pump modules to increase brightness includes generating one or more pump beams from respective diode lasers at a first wavelength in a diode laser package, generating one or more pump beams from respective diode lasers at a second wavelength different from the first wavelength in the diode laser package, wavelength combining at least one of the pump beams at the first wavelength with at least one of the pump beams at the second wavelength to form one or more combined pump beams, and receiving the combined pump beams in a pump fiber coupled to the diode laser package. Laser systems can include multi-wavelength pump modules and a gain fiber having a core actively doped so as to have an absorption spectrum corresponding to the multiple wavelength, the gain fiber situated to receive the pump light and to produce an output beam at an output wavelength.
