Multiple-source laser display system

A method, comprising:

• modulating in time and emitting a first color light from a first array comprising a plurality of lasers, each laser having a maximum output power less than 10 mW;
• modulating in time and emitting a second color light from a second array comprising a plurality of lasers, each laser having a maximum output power less than 10 mW;
• optically coupling an optical element to the first array and the second array to form a light that impinges on a steering element;
• modulating the steering element in time to direct the light in an angular range in which the steering element is optically coupled to an optical combiner;
• and
• redirecting the light by the optical combiner to an eyebox to form a substantially white image having a brightness of at least 1000 nits.

A laser-scanning display system comprising:

• a blue array comprising a plurality of blue vertical-cavity surface-emitting lasers (VCSELs) optically coupled to a first micro-lens array comprising a plurality of lenses, each lens optically coupled to a laser in the blue array;
• a green array comprising a plurality of green VCSELs optically coupled to a second micro-lens array comprising a plurality of lenses, each lens optically coupled to a laser in the green array;
• a red array comprising a plurality of red VCSELs optically coupled to a third micro-lens array comprising a plurality of lenses, each lens optically coupled to a laser in the red array;
• a steering element optically coupled to the first, second, and third micro-lens arrays;
• and
• an optical combiner optically coupled to the steering element, wherein
• the lenses of the micro-lens arrays are configured such that at least 20% of an optical power characterizing emission of light emitted from each VCSEL reaches the steering element.

An augmented reality display system comprising:

• a first plurality of blue vertical-cavity surface-emitting lasers (VCSELs), wherein each VCSEL has an output power less than 10 mW;
• a second plurality of green VCSELs;
• a third plurality of red VCSELs;
• an optical system optically coupled to the third, second and third pluralities of VCSELs and configured to form an image from light emitted from the third, second and third pluralities of VCSELs;
• and
• an eye-tracking element, wherein electrical powers controlling each VCSEL in the first, second and third pluralities are modulated based on data from the eye-tracking element to facilitate formation of the image.
