    摘要： A powerful high-brightness laser pump modules is configured with a plurality of spaced laser diodes each generating a light beam at a pump wavelength, and respective groups of optical components guiding the light beams along parallel light paths. The groups of the optical components each include a lens assembly and a bending mirror configured to couple the beam light into an output fiber which is common to all groups of the optical component. At least one optical component of each group is provided with a dielectric layer capable of preventing propagation of a backreflected light toward laser diodes at a wavelength different from the pump wavelength.

    摘要： A multi-layer laser diode mount is configured with a submount made from thermo- and electro-conductive material. One of the opposite surfaces of the submount supports a laser diode. The other surface of the submount faces and is spaced from a heatsink. The submount and heatsink are configured with respective thermal expansion coefficients (“TEC”) which are different from one another. The opposite surfaces of the submount are electroplated with respective metal layers one of which is bonded to a soft solder layer.In one aspect of the disclosure, the mount is further configured with a spacer having the same TEC as that of the submount and bonded to the soft solder layer. A layer of hard solder bonds the spacer and heatsink to one another.In a further aspect of the disclosure, the electroplated metal layer in contact with the other surface of the submount is hundred- or more micron thick. The soft solder is directly bonded to the heatsink.In both aspects of the disclosure, a temperature of a p-n junction of the laser diode remains substantially constant within a 0 to 2° C. temperature range through a predetermined amount of several hundred of repeated thermo-cycles which is indicative of uncompromised integrity of the soft solder.

    摘要： A module is configured with a housing enclosing a diode laser. Fast and slow axes collimators are located behind the rear facet of the laser, which along with a front facet, defines an intra-cavity cavity of the laser. The facets are partially transmissive to light and therefore emit laser light. A wavelength selective optical element is aligned with the collimators and configured to reflect light emitted through the back facet and processed by collimators back into the intra-cavity. As a result, the laser beam is emitted through the front facet at a wavelength locked on the desired wavelength of the optical element. A delivery fiber is mechanically coupled to the front facet of diode laser and configured to receive and guide the emitted laser beam along the path of light.

    摘要： Field emitter as a source of electrons and method for making are provided. The emitter is formed by growth of a nitride compound of a group III element or alloys of group III elements on a substrate having a lattice mismatch with the thin film. The lattice mismatch causes columnar growth in the film. The micro columns have tips, thus forming an array of crystalline microtips of the low work function nitride material. The nitride compound is doped during growth. Gallium nitride grown on (111) silicon and doped with silicon produces a surface having low threshold electric field for emission and high current per unit area.
