Color-coded light intensity distributions of the three K-lasers: for each unit, the three diodes (800 nm, 905 nm, 970 nm) were recorded individually as well as all diodes simultaneously and the K-lasers’ intense-super pulse (ISP) mode. Magenta represents the lowest light intensity, and red represents the highest light intensity. Projections of beam profiles along the horizontal and vertical axes are shown as white lines behind the intensity distributions. Recordings were taken with the K-lasers’ zoom objective set to sizes 1 and 3. The intensities of each recording were maximized by adjusting the camera exposure time.
