Abstract
Techniques are provided for increasing a laser light's spectral linewidth while simultaneously improving how a laser is controlled by causing the laser to operate at higher power levels. An illumination energy value for a pixel and an illumination time period for the pixel are both determined. A number of laser pulses that are to be emitted by the laser assembly to illuminate the pixel during the illumination time period is also determined. This number is based on the illumination energy value for the pixel. Then, within the illumination time period and in accordance with the determined number of laser pulses, the pixel is illuminated by causing the laser assembly to emit one or more laser pulses that cause the pixel to be illuminated at the illumination energy value.
