Claim 0:
1. A barcode imager comprising:
an imager configured to capture images over a field of view of the barcode imager each image is to be captured during a frame duration of the barcode imager;
an aiming assembly comprising a green laser source and configured to generate a green laser aiming pattern within the field of view of the barcode imager and comprising an emission having a wavelength within 495 nm-570 nm; and
a controller configured to control the green laser source to generate the green laser aiming pattern as a single aiming pulse per each frame duration and having a duty cycle over each frame duration that simultaneously satisfies a frame duration-independent, peak pulse optical power constraint and a frame duration-dependent heat dissipation constraint,
wherein the duty cycle of the aiming pulse is a non-overlapping duty cycle such that a sensor exposure window of the imager and the aiming pulse do not overlap during the frame duration.
