Focusing of diode laser beams: a simple mathematical model: reply to comment.
Gaussian and Lorentzian-Gaussian models for the elliptical cross-section beams of GaAs diode lasers are reexamined, emphasizing that the simplicity of the Gaussian model vanishes in many practical applications where laser beams are truncated by the collimating lens. The Lorentzian model is advantageous because the width of the distribution may be estimated from the composition of the semiconductorjunction.
