Phase locking of an array of lasers is a highly effective method in beam shaping because it
increases the output power and reduces the lasing threshold. Here, we show a conceptually …

Diode-laser systems have a good chance to be used as light sources for direct applications.
For this purpose a large number of relatively weak light bundles originating from individual …

Over the last two decades, the search for a compact, high-power semiconductor source has
produced many designs and concepts for monolithic diode-laser arrays and optical …

The term photonic wire laser is now widely used for lasers with transverse dimensions much
smaller than the wavelength. As a result, a large fraction of the mode propagates outside the …

This thesis explores the design, construction, and applications of the optoelectronic swept-
frequency laser (SFL). The optoelectronic SFL is a feedback loop designed around a swept …

The equations for N coupled semiconductor lasers in a ring geometry are considered. The
lasers are coupled either in series or parallel. Parallel coupling is known as a strong …

We find that the natural antiphasing tendency in linear solid-state laser arrays can be
overcome by an injected field, even if the N elements are not identical. We derive a condition …

The far-field emission characteristics and spectral purity of photonic-crystal distributed-
feedback (PCDFB) lasers, in which the grating is defined on a two-dimensional lattice that is …

10 W peak-pulsed power emitted in a beam pattern 2× diffraction limit (DL) is obtained from
a 40-element, 200 µm-aperture Al-free phase-locked antiguided array (λ= 0.98 µm). 60% of …

Near‐diffraction‐limited cw operation at 1 W power level is demonstrated, for the first time,
from all‐monolithic, phase‐locked diode‐laser arrays. In pulsed operation purely diffraction …
