摘要	Apparatus and methods combine visible light output from two or more laser light sources emitting at different wavelengths to provide an illumination beam for illumination inside a human or animal body during a diagnostic or surgical procedure. An ophthalmic procedure device comprises a housing, a blue diode laser positioned within the housing, a green diode laser positioned within the housing, a red diode laser positioned within the housing, an optical fiber connector attached to the housing, a lens, and beam combining and beam steering optical elements arranged to collinearly combine an output beam from the blue diode laser, an output beam from the green diode laser, and an output beam from the red diode laser to form an illumination beam and direct the illumination beam through the lens to focus into a core of an optical fiber illumination probe that may be externally attached to the optical fiber connector.
其他摘要	装置和方法组合来自以不同波长发射的两个或更多个激光光源的可见光输出，以在诊断或外科手术过程中提供用于在人体或动物体内照射的照射光束。一种眼科手术装置，包括壳体，位于壳体内的蓝色二极管激光器，位于壳体内的绿色二极管激光器，位于壳体内的红色二极管激光器，附接到壳体的光纤连接器，透镜和光束组合和光束控制光学元件，用于共线组合来自蓝色二极管激光器的输出光束，来自绿色二极管激光器的输出光束和来自红色二极管激光器的输出光束，以形成照明光束并将照明光束引导通过透镜聚焦到光纤照明探头的核心中，该探测器可以从外部连接到光纤连接器。
主权项	An illumination device for use in an ophthalmic procedure, the illumination device comprising: a housing; a blue diode laser positioned within the housing; a green diode laser positioned within the housing; a red diode laser positioned within the housing; an optical fiber connector attached to the housing; a lens; and beam combining and beam steering optical elements arranged to collinearly combine an output beam from the blue diode laser, an output beam from the green diode laser, and an output beam from the red diode laser to form an illumination beam and direct the illumination beam through the lens to focus into a core of an optical fiber illumination probe externally attached to the optical fiber connector; wherein the illumination beam produces a speckle intensity pattern when delivered through the optical fiber illumination probe to illuminate internal eye tissue during the ophthalmic procedure, and the illumination beam is incident on an optical element within the housing configured to oscillate at greater than or equal to about 30 Hertz over a distance or angular range sufficient to translate speckles in the speckle pattern by at least one speckle diameter, thereby blurring the speckles and smoothing out the intensity pattern as observable by a human observer having normal visual perception.
