摘要： A method and apparatus is provided that enables an IBC system to operate over a large field angle. As a consequence, wide laser gain arrays can be used providing greater control over the output power and the bandwidth of the IBC system. The IBC resonator cavity is comprised of a reflector, preferably deposited on the back facets of the gain element array, and an output coupler. Interposed between the array and the output coupler is a wavelength dispersive element, such as a diffraction grating, and a collimating optic. A lens system, comprised of either a single cylindrical lens, a single cylindrical lens in combination with an array of orthogonally positioned cylindrical lens elements, or an array of individual lens elements, is located between the laser gain array and the collimating optic. At a minimum, the lens system reduces the divergence of the light from each emitter in the fast axis, thus allowing smaller, less optically complex optics to be used for the IBC resonator optics.

摘要： A method and apparatus for generating a display is provided. In the disclosed system, each color required by the display is generated by incoherently combining the beams of tens or hundreds of individual lasers. In order to achieve a full color display, three independent IBC systems are used to generate the required three colors (e.g., red, green and blue). The output from each IBC system is modulated and the three beams are combined to form a single, modulated output beam that is directed to a display scanner.

摘要： A single piece optic for coupling the output of a diode laser array into an optical fiber array is provided. The coupling optic has a planar back surface which, during use with a diode laser array, is positioned substantially parallel to the front face of the laser array. The coupling optic is fabricated from a single substrate and is comprised of a plurality of optical elements. Depending upon the technique used to fabricate the optical elements, the individual optical elements may be trapezoidally-shaped or rectangularly-shaped. The front surface of each optical element is tilted, thus preventing reflected laser radiation from resonating within the diode laser's emitters. Preferably the wedge angle for the tilted front surface is greater than 2 mrad, thus accomplishing the goal of limiting feedback into the emitters, and less than 4 mrad, thus reducing beam steering. Additionally each optical element is shaped to reduce the divergence of the emitters in the fast axis, thus allowing the output from each emitter to be effectively coupled into the corresponding optical fiber.
摘要翻译：提供了用于将二极管激光器阵列的输出耦合到光纤阵列中的单片光学器件。耦合光学器件具有平坦的后表面，其在与二极管激光器阵列的使用期间基本上平行于激光器阵列的前表面定位。耦合光学器件由单个衬底制造并且由多个光学元件组成。根据用于制造光学元件的技术，各个光学元件可以是梯形的或矩形的。每个光学元件的前表面倾斜，从而防止反射的激光辐射在二极管激光器的发射器内谐振。优选地，倾斜前表面的楔角大于2mrad，从而实现将反馈限制到发射器中的目标，并且小于4mrad，从而减小波束转向。此外，每个光学元件被成形为减小发射器在快轴上的发散度，从而允许来自每个发射器的输出被有效地耦合到相应的光纤中。

摘要： The present invention is directed to a system and method which utilize an incoherently beam combined (IBC) laser. The IBC laser includes a plurality of emitters with each of the emitters possessing a partially reflective surface on their front facet. The partially reflective surface causes resonant wavelengths to be defined. In certain embodiments, the system and method arrange the external cavity and emitter spacings of the IBC laser such that the center feedback wavelength provided to each emitter is an etalon resonant wavelength. In other embodiments, the range of feedback wavelengths is adapted so that it is greater than the free spectral range (the separation in wavelength space between adjacent etalon resonant wavelengths).
