Abstract

It is shown that the radiation pattern of laser diode radiation can quantitatively be analyzed without labor-intensive and expensive measurements of the radiation intensity distribution in the near-field zone. Formulas are obtained in the explicit form, which analytically describe the radiation pattern of laser diode radiation in free space, and a simple algorithm is developed for determining the fundamental lasing mode.
