Stable phase-locking of a VCSEL array of N equals 16 emitters with the master laser on the same chip is demonstrated. To accomplish the injection-locking a very small portion of the master radiation is seeded frontally into the 16 slave lasers. All V

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 oscillators have to be coupled to a single powerful beam. The cou

It was proven by powder x‐ray diffractometry and by energy dispersive x‐ray analysis (EDX) that after ablation of the ceramic YBa2Cu3O7−x target by the excimer laser pulses the original composition of the target remained unchanged. The depth of

Incoherent superpositioning of radiation from a single-mode fiber bundle with 200 mW output power per fiber allows torealize power densities of 2 MW/cm2 (. = 1 tm, NA = 0.2). The total power being directly scalable with the number offibers (angle mul

Laser diodes with diffraction-limited beam quality offer high power densities of the order of 107 - 108 W/cm2, but are limited in output power to some watts. Scaling to higher powers has to be realized by superposition of a number of laser diodes. Co

Laser diodes with diffraction limited beam quality offer high power densities of the order of iO - 108 W/cm2, but are limited in output power to some Watts. Scaling to higher powers without using a solidstate laser converter has to be realized by inc

In this paper the term microstructuring is used for two different tasks: (1) The growing of precise epitaxial layers by means of laser generated particle streams. This process may be treated as a laser assisted molecular beam epitaxy. (2) The lateral
