This paper details the importance of brightness in relation to laser beams. The 'brightness' of
lasers is a term that is generally not given much attention in laser applications or in any …

We demonstrate the spectral beam combining of a diode laser stack, which contains three
970nm Mini-Bars along the fast-axis direction, in an external cavity. At the pump current of …

We demonstrate spectral beam combining of a 980 nm tapered diode laser bar. The
combined beam from 12 tapered emitters on the bar yielded an output power of 9.3 W at 30 …

We have coherently combined a high-power broad-area laser diode array by using a
feedback loop closed off-axis external Talbot cavity. The off-axis feedback from two gratings …

Stripe-array diode lasers naturally operate in an anti-phase supermode. This produces a
sharp double lobe far field at angles±α depending on the period of the array. In this paper a …

Diode lasers have proven to be versatile light sources for a wide range of applications.
Nonlinear frequency conversion of high brightness diode lasers has recently resulted in …

We proposed a modified off-axis spectral beam combining method, based on the concept of
selective feedback. A high reflectivity mirror with a fixed width was used to select and couple …

A novel spectral beam combining (SBC) approach based on off-axis feedback in a V-shaped
external cavity (VSBC) was proposed and demonstrated. A highly reflecting mirror was used …

摘要半导体激光器由于受波导结构和芯片封装等因素的限制, 其快慢轴方向上的光束质量差距较
大, 主要用作抽运源, 即被当成亮度转换器使用, 很难作为高亮度光源直接应用 …

The efficiency, threshold characteristics, and the stability of spectral beam combining (SBC)
of diode laser array had been studied based on different output couplers (OC). It was found …
