Using a quantitatively calibrated imaging system and specially fabricated tapered lasers with windowed n-contacts, the authors image the spontaneous emission distribution inside two different laser cavities as a function of injection current. In the

Experimental measurements of the spatial distribution of the spontaneous emission produced inside the cavity of a 4° 980 nm tapered laser are presented and compared with the results of a 2.5 D half-space, hot-cavity simulation. A custom device with

We present a simulation tool useful to optimize the design of semiconductor tapered lasers and to study the physical processes inside of them. This is achieved by using a state-of-the-art quasi-three-dimensional (quasi-3-D) electrical and thermal mod

With a view to improve the power level and brightness of semiconductor pump lasers, we have resorted to a scalable implementation and achieved spectral beam combining through a low-quality-factor external cavity. For that purpose, a high-power single

In this letter we present a new fully index-guided tapered laser design showing a balance between the competing mechanisms modifying the far-field divergence at high operating powers. Simulations and experimental investigations of this device show a

We demonstrate high brightness mini-bars (emissive region is 2.6 mm wide) of tapered laser diodes, reported for the first time on Al free materials, with an output power of 15.6 W at 23.5 A, 20/spl deg/C, having a Gaussian far-field shape with a low

We report laser and self-doubling experiments on a Nd:GdCOB crystal in a diode-pumped plano-plano cavity. We have obtained 22 mW diffraction-limited green output power at an absorbed pump power of 1.2 W.
