A method for operation of a red, green, blue, RGB, laser assembly used for creating an image in a mixed-reality environment in order to increase a spectral linewidth of laser light that is emitted by the RGB laser assembly, the method being performed by a computer system that includes the RGB laser assembly, wherein the laser light is directed via a waveguide to an eye of a user of the computer system, the method comprising: identifying a set of one or more pixels that are to be irradiated by any one or a combination of one or more red lasers, one or more green lasers, or one or more blue lasers that are included within the RGB laser assembly; for each pixel in the set of one or more pixels, cause the any one or the combination of the one or more red lasers, the one or more green lasers, or the one or more blue lasers in the RGB laser assembly to pulsedly irradiate each pixel by performing at least the following: initially operating the RGB laser assembly below a laser threshold such that the RGB laser assembly is refrained from irradiating any pixels in the set of one or more pixels; energizing the RGB laser assembly above the laser threshold to cause the RGB laser assembly to begin to irradiate at least one pixel in the set of one or more pixels with laser light; causing the at least one pixel to be irradiated with the laser light for a selected period of time lasting no longer than 15 nanoseconds (ns), wherein, while the at least one pixel is irradiated with the laser light, an intensity of the laser light is set to not exceed a pre-determined optical power level, wherein the pre-determined power level is based on a resolution requirement associated with the pixel and/or other attributes for that particular pixel, wherein different pixels are associated with different selected periods of time, wherein the different selected periods of time are based, at least in part, on a location of each corresponding pixel in a field of view of a display for the computer system; and after the selected period of time elapses, operating the RGB laser assembly below the laser threshold such that the RGB laser assembly is again refrained from irradiating any pixels. identifying a set of one or more pixels that are to be irradiated by any one or a combination of one or more red lasers, one or more green lasers, or one or more blue lasers that are included within the RGB laser assembly;
