Multiple-input-coupled illuminated multi-spot laser probe

A method of multiplexing a multi-spot pattern of laser light beams with a illumination light beam comprising:

• directing a laser light beam to an optical element for collimating the laser light beam, the laser light beam having a wavelength contained within at least one of two narrow bands of an electromagnetic spectrum of light;
• directing the collimated laser light beam to a diffractive optical element (DOE) configured to create a multi-spot laser pattern of laser light beams;
• directing the multi-spot pattern of laser light beams to a beamsplitter;
• directing an illumination light beam to the beamsplitter, wherein the beamsplitter is configured to reflect the at least two narrow bands of the electromagnetic spectrum of light and transmit portions of the electromagnetic spectrum of light not contained within the at least two narrow bands of the electromagnetic spectrum, thereby multiplexing the multi-spot pattern of laser light beams and a transmitted illumination beam;
• directing the multiplexed multi-spot pattern of laser light beams and transmitted illumination beam to a condensing lens for focusing the multiplexed multi-spot pattern of laser light beams and transmitted illumination beam onto an interface plane of a proximal end of a multi-core optical fiber cable.
