    Abstract: A VCSEL 101 comprising an optical cavity having an optical loss and a loss-determining element 117 coupled to the optical cavity. The loss-determining element 117 progressively increases the optical loss of the optical cavity with increasing lateral distance from the optical axis 105. The optical cavity includes a first mirror region 111, a second mirror region 107, a plane light-generating region 125 sandwiched between the first mirror region 111 and the second mirror region 107, perpendicular to the optical axis 105, and an element 113 that defines the lateral extent of the optical cavity in the plane of the light-generating region 125. The first mirror region 111 and the second mirror region 107 are both conductive and have opposite conductivity modes.

    Abstract: A simple and compact laser resonator is proposed which makes it possible to symmetrically operate a gain medium, preferably a semiconductor, which possesses more than one channel of emission. As a result higher output powers and/or better beam qualities and/or better spectral characteristics can be achieved. The resonator is very compact and ideally comprises only three optical elements: a laseractive gain medium (1), a cylindrical collimation lens (5), and a prism (6) which is adapted to the angle between the two emissions (4) and which carries a beam splitter (7) and a feedback mirror (9) on its faces. Preferably the gain medium (1) possesses a feedback element (2) and an antireflective coating (3) on its faces. If no antireflective coating (11) is desired the same effect can be achieved by arranging the angle of incidence to fulfill the Brewster-condition. In a preferred embodiment the gain medium (1) is a high-power diode laser chip with an internal stripe-array and/or the laser resonator is unstable along the direction parallel to the epitaxial layers. In alternative embodiments the feedback element (9) is wavelength selective like a grating, a dielectric filter, a holographic element or a volume Bragg grating.

    Abstract: The present invention provides for the coupling of laser diodes into electromagnetic radiation transmitting fibers wherein coupling efficiency is improved by improving the spatial brightness of multi-mode diode lasers as they are coupled into double-clad fibers. A Bragg grating 100 is fabricated into the core 102 of a double-clad fiber 104 coupled to a multi-mode diode laser 106. The output 108 from the multi-mode diode laser 106 is coupled into the core 102 and inner cladding 110 of the double-clad fiber by proximity or by one or more focusing objectives 112. The Bragg grating 100 in the core 102 of the double-clad fiber 104 is written at the wavelength of the multi-mode diode laser 106. The original output 108 from the multi-mode diode laser 106 strikes the Bragg grating 100 which reflects feedback 114 back to the diode laser 106.
