nm which produces a blue output light suitable blue lasers may use for example ingan semiconductor lasers or dpss lasers to generate a suitable monochromatic blue output light at a frequency between the range of 445 475 nm the light from each of the laser light sources 180 182 184 is transmitted through optical components 186 such as coupling lenses to focus and or direct the output light beams onto dedicated optical fibers 188 which extend through the interior lumen 176 of the cannula 175 suitable fibers may have a diameter of less than approximately 100 although larger fibers may be appropriate for certain applications the optical fibers 188 may terminate within at the distal end of or past the distal end of the cannula 175 the red green and blue light beams transmitted from the ends of the optical fibers 188 combine to generate a white polychromatic output light beam in one example 11 lumens of white light formed from a red beam at 632 nm a green beam at 532 nm and a blue beam at 473 nm would involve approximately 11 mw of red laser light 14 mw of green laser light and 11 mw of blue laser light respectively it is understood that additional optical components or optical fiber geometries not shown may be used to further direct and combine the monochromatic light beams into a white output beam fig5 depicts an endoillumination system 190 which is substantially similar to the system 170 but in this embodiment the system further includes a connector 192 for removably connecting probe 194 to handpiece 196 as describe above for fig2 the use of a connector allows the handpiece to be reused and the probe to be disposable fig6 depicts an endoillumination system 200 which includes a handpiece 202.
