Although LEDs are useful, there are limitations that it is desirable to overcome according to the embodiments described in the following disclosure.

The present invention is a laser composed of a laser diode containing gallium and nitrogen, a wavelength converter member such as a phosphor, and an optical cable or fiber member that conveys the laser-based light to the desired illumination location for illumination. A base fiber-coupled white light system or device is provided. In some embodiments, white light is transmitted from a laser-based light source to a remote illumination location in a light transmission fiber. The high brightness from laser-based white light sources allows for substantially higher optical coupling efficiencies of white light to light transmission cables compared to other solid-state lighting technologies such as LED technology. For example, laser-based white light sources can provide brightness in the range of 500-1000 cd/mm ² , 1000-2000 cd/mm ² , 2000-20000 cd/mm ² , or higher. These high luminance values range from about 2.5 times to about 100 times that of LED light sources. This significantly higher brightness or brightness enables substantially better optical coupling efficiency in fiber optic cables. For example, for a 1 mm diameter core fiber optic cable, the coupling efficiency for a laser-based white light source can range from 50% to about 90%. For LED-based white light sources, the optical coupling efficiency can range from 2% to about 10% for the same fiber optic cable. That is, laser-based white light sources are brighter and therefore have better coupling efficiency of white light into transmission fibers than LED light sources. Laser-based white light sources therefore offer new and unique opportunities to create white light systems and devices that offer strong advantages over LEDs.

In one embodiment, a laser-based fiber-coupled white light system includes a material containing gallium and nitrogen and is configured to emit coherent electromagnetic radiation having a first wavelength in the range of 385 nm to 495 nm. It includes a laser device configured as a pump source having an output end. Further, the white light system includes a phosphor plate used as a wavelength converter and an emitter mounted in free space and having a receiving surface for receiving laser emission in a substantially normal direction. The phosphor plate converts laser emission of the first wavelength into phosphor emission of a second wavelength longer than the first wavelength. The phosphor emission is at least partially mixed with the laser emission within the phosphor plate to transmit through the phosphor plate to produce white emission from an output surface opposite the light receiving surface. In some embodiments, the coherent electromagnetic radiation having the first wavelength of the excitation beam emitted from a laser diode is scattered by the phosphor plate rendering the electromagnetic radiation incoherent. The emission of wavelength-converted electromagnetic radiation from the phosphor plate having said second wavelength is characterized by an incoherent and Lambertian emission pattern. As a result, white light consisting of at least said second wavelength electromagnetic radiation, or both said first wavelength electromagnetic radiation and said second wavelength electromagnetic radiation, is incoherent. As a result, the fluorescent plate may emit white light in a Lambertian pattern. Furthermore, the white light system includes a support member that supports the laser device and/or the fluorescent plate. Additionally, the white light system includes a fiber coupled to the phosphor plate to capture white light emission with an efficiency of at least 20% and transmit or distribute the white light emission. The leaky fiber may be a bundle of leaky fibers. For example, the fibers may be bundles of fibers composed of glass fibers or plastic fibers.
