摘要： An improved high power spatial filter, system and method. In the system, an optical fiber is disposed inside a ferrule channel structure, and the channel structure is aligned with a focusing lens system. The end of the fiber is at a distance D from the channel opening that faces the focusing lens system, and D is determined by the system's numeric aperture factor and the cladding thickness of the optical fiber.

摘要： A twin fiber laser arrangement is configured with active and passive fibers supporting respective signal and pump lights and a reflective coating surrounding the fibers along a section of the arrangement. The passive fiber has regions covered by respective protective layer and coating-free regions alternating with the layer covered regions, wherein the reflective coating is configured to overlap the protective layer which shields the end of the reflective coating from high power pump light.

摘要： A gain module, operative to output a laser light coupled into a laser system, is structured with at least one gain element radiating the laser light and a spectrally-selective element. The spectrally-selective element includes a slab of photosensitive material and two parallel feedback and isolating Bragg mirrors recorded in the slab. The feedback Bragg mirror is operative to provide a wavelength-dependent feedback so as to cause the laser chip to generate the laser light at the resonance wavelength of the feedback Bragg mirror. The isolating Bragg mirror is automatically adjusted to retroreflect a backreflected signal light, which is generated by the laser system at a signal wavelength different from the resonance wavelength, upon positioning the feedback mirror orthogonally to the laser light.

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 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.
