Abstract

As a contribution to the current intense research efforts on wide band‐gap semiconductor devices which are directed towards the development of commercial blue laser diodes, in this issue's Editor's Choice the optimization of the waveguide structure, to achieve stable laser mode operation, is investigated.

The cover picture shows the near‐field intensity distribution of the fundamental and first order lateral modes of a blue (Al,In)GaN laser diode together with the double longitudinal mode comb associated with these modes.

The first author, Ulrich T. Schwarz, works on optical spectroscopy, characterization, and simulation of blue laser diodes and LEDs. Apart from semiconductor optoelectronics, the focus of his scientific interest is on modern optics, covering propagation invariant Bessel beams, Ince‐Gaussian beams and optical vortices.

## Abstract Height and width of the ridge forming the laser diode waveguide determine threshold current density and lateral mode stability. We measure the optical near‐field of the laser mode and simulate the two–dimensional mode distribution including waveguide losses and optical gain. The simulat

The influence of intracavity second harmonic generation on the mode competition in a double-mode diode-pumped Nd:YAG laser is studied theoretically and experimentally. Various configurations of the optical cavity with II-type phase-matching frequency-doubling crystals are considered. The conditions
